Next Generation User Guide

CHAPTER ONE – Introduction

NEOGEN® ’s AccuPoint Advanced Next Generation (NG) sanitation monitoring system is a lightweight, handheld diagnostic tool used to validate and verify a sanitation program’s effectiveness by detecting organic residues remaining on surfaces and in liquids after cleaning when using the AccuPoint Advanced samplers. The system is composed of three primary components: an electronic luminometer; fully self-contained single-use samplers, and data manager software.
When used with AccuPoint Advanced ATP samplers, the system will detect adenosine triphosphate (ATP) collected in the sample and report the measurement in relative light units (RLUs). RLU thresholds are established by a facility to reflect effective cleaning practices.The instrument compares the measured level of ATP to the established thresholds and reports the result as a pass, marginal, or fail.
The system will record the time, date, specific test site location, site group, and area information in addition to the recorded RLU and result. The AccuPoint Advanced NG instrument also gives users the ability to enter notes on individual test results. This information can be uploaded to the data manager software for additional review and reporting.
NEOGEN continually works to improve its product lines, and nowhere is that more evident than with the AccuPoint Advanced system. With the AccuPoint Advanced system, innovations allow for better functionality and service than ever before.
These innovations include the advanced samplers, which feature a bioluminescent reaction in a liquid-stable solution. This allows for a more consistent reaction that provides a more consistent result. This chemistry also creates a more robust reaction that has the benefit of providing greater sensitivity through a clearer distinction between very low levels of ATP. The AccuPoint Advanced NG instrument offers enhanced navigation, touch screen, wireless data transfer capability, and robust design to take your sanitation monitoring program to the next level.
NEOGEN’s AccuPoint Advanced system can also be used to test dairy products to ensure proper pasteurization when using high-temperature, short time (HTST) processing equipment. The AccuPoint Advanced Alkaline Phosphatase sampler is a chemiluminescence-based test that allows the user to determine whether a milk sample has been properly pasteurized or is contaminated with raw milk. A sample of milk to be tested is collected using the sampler and exposed to the substrate solution contained within the sampler body. After a brief incubation, the amount of light generated by the interaction of the substrate with alkaline phosphatase naturally present in raw milk is detected on the AccuPoint Advanced NG instrument and reported in mU/L.
When used with the AccuPoint data manager version 4.0 software (or later), the AccuPoint Advanced NG instrument can be set up to record the testing results at user specified test sites, along with the date, time, and user. The test site information is entered into the data manager program and uploaded to the AccuPoint instrument. The user simply navigates to the correct site and takes the test. The AccuPoint Advanced NG instrument has built in RFID functionality that can be used to automatically identify test locations that are set up with RFID tags. The user simply brings the unit close to the RFID tag and the correct site is automatically identified for that test.
Up to 3,000 unique testing sites can be tracked with each AccuPoint Advanced NG instrument. Up to 4,000 test results can be stored at any time and are not lost if the instrument loses power. An integrated, rechargeable lithium-ion battery provides power.

CHAPTER TWO – Operating Principles and Technology

The AccuPoint® Advanced ATP samplers utilizes ATP bioluminescence to determine the cleanliness of test samples. ATP is a chemical compound found in all living cells, including bacteria, food debris, yeast, and mold. Bioluminescence is a chemical reaction that produces light. ATP bioluminescence occurs when ATP from a sample comes into contact with luciferase, an enzyme found in fireflies, and luciferin, a substrate. The amount of light emitted in this reaction is proportional to the amount of ATP in a sample. After a sample is taken, the sampler is pressed into its cartridge, breaking its seal and initiating the mixing of reagents. The reaction takes place within the cartridge, and a detector in the instrument measures the amount of light produced. The reading is displayed on the screen in RLUs. According to preset limits, an icon is displayed indicating a pass, marginal, or fail result. These limits are defined by the operator, by the company’s quality system, or by using the system presets.

CHAPTER THREE – Operating Guidelines and Precautions

Electrical Warnings
The instrument should be used according to the instructions provided in this manual. If used otherwise, the electrical protection provided may be impaired.
The power source for charging the AccuPoint® Advanced NG sanitation monitoring instrument must be adequate and stable. For optimal performance, use only the wall adaptor provided with the AccuPoint Advanced NG instrument. Do not operate the instrument in an explosive atmosphere, operate the instrument with any covers or parts removed, and do not attempt to make adjustments, replacements, or repairs to this instrument. Only a certified NEOGEN® service representative should service the instrument.
Proper Use of Sampler Cartridges
Use only AccuPoint Advanced sampler cartridges with the AccuPoint Advanced NG instrument. Be sure to refrigerate the samplers at 2–8°C (35–46°F). Within this temperature range, samplers may be stored until their expiry date. Also, note that samplers must be warmed to room temperature before use. Samplers can be stored at room temperature for up to two weeks. After removing sampler cartridges from the bag, be sure to reseal and refrigerate the bag at 2–8°C. Do not touch the tip of the sampler or let the tip touch any other surface before testing. Sampler tips should only come into contact with the test surface or sample.
Additionally, do not sample pools of liquid with AccuPoint surface samplers. You will want to allow excess liquid to dry before testing surfaces. Use AccuPoint water samplers for testing liquids. Be sure to remove and properly dispose of samplers after each reading from the instrument. The sampler reagents and their cartridges are non-toxic and may be disposed of without any special considerations.
Proper Care of the Instrument
To maintain proper care, be sure to keep the sampler compartment door closed when the instrument is not in use. Be sure to minimize the time the door is open while inserting and removing samplers. The instrument uses a highly sensitive photodetector and should be protected from direct sunlight.
Do not place the instrument in direct sunlight when the sampler door is open, or store in sunlight, where it can be exposed to a rapid increase in temperature. Furthermore, you will need to work with clean hands when using the instrument and avoid contact with liquids on the outside or inside of the unit. Immediately wipe off any liquids to prevent electrical shorting or contamination. Also, be sure the outer surface of the sampler cartridge is clean and dry before inserting it into the unit. Do not insert the sampler in the unit without its cartridge, and do not attempt to disassemble the instrument. The battery is to be replaced by authorized personnel only. There are no user-serviceable parts. Use the supplied line power cord for charging with the provided wall charger power supply or from your PC USB port. The use of any other power supply may damage the unit and invalidate the warranty. The power supply is capable of using an AC voltage of 110 to 240 VAC and 47 to 63 Hz and should be applied for indoor use only.
Note: In accordance with part 15 of the FCC rules, changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
Cleaning the Instrument
Clean the outer surfaces of the instrument with a disinfectant wipe approved by your organization or company. If a disinfectant wipe is not available, a solution of 70% isopropyl alcohol can be applied to a clean, cotton or lint- free cloth and used to clean and disinfect the instrument. Cleaning the inside of the optical tube may be necessary if aberrant test results occur. At the bottom of the optical tube is a lens that may be contaminated. To clean the lens, use the AccuPoint® Advanced NG cleaning swab moistened with a solution of isopropyl alcohol (>70%). Be sure to turn the instrument upside down while cleaning the lens. After cleaning, use a fresh cleaning swab to thoroughly dry the lens area. CAUTION: If liquid spills inside the sampler compartment, turn the instrument off and use the AccuPoint Advanced NG cleaning swab to dry the interior surfaces.
Note: The use of unapproved solvents and swabs inside the sampler compartment may damage the unit or leave behind swab debris, adversely affecting instrument performance and test results.

CHAPTER TEN – Additional Features

The AccuPoint® Data Manager Software
The AccuPoint Advanced NG instrument can be utilized with the data manager software version 4.0 (or later) to upload test site information and to download test results. The use of this combination allows for the compiling, tracking, and analyzing of facility-wide testing results over its entire population of users and instruments. The procedure starts with the definition of a test plan in the data manager software. This test plan identifies all of the testing sites in the facility that could be tested and assigns pass, marginal, and fail thresholds to each site. Once the test plan is defined, uploading the information to the instrument will allow the user to select the appropriate site before taking each test. The results, along with the time, date, user, site name, site group, and area can then be uploaded to the software for tracking and analysis.
Sampler Type: Surface, Liquid, or Alkaline Phosphatase
The AccuPoint Advanced NG instrument operates in two sampling modes: surface and liquid. Both the AccuPoint surface and access samplers are designed to be read in surface mode. The AccuPoint liquid sampler is read in liquid mode. A water droplet symbol will appear on the display when the instrument is in liquid sampling mode. If utilizing the AccuPoint data manager software and the test plan has been uploaded to the AccuPoint Advanced NG instrument, it will automatically change to the appropriate testing mode, surface or liquid, when navigating to the testing site.
If utilizing NEOGEN® ’s new AccuPoint Advanced Alkaline Phosphatase tests, this should be designated upon the installation of the software. After enabling alkaline phosphatase functionality, the Alk Phos test sites will be automatically loaded into the instrument when the overall test plan is synced to the AccuPoint Advanced NG instrument. For additional information on software setup and use, refer to the data manager user guide.
Setting the Pass, Marginal, and Fail Thresholds
The AccuPoint Advanced NG instrument comes programmed with default threshold settings of 0–149 RLU as pass, 150–299 RLU as marginal, and 300 RLU and higher as fail. These thresholds can be changed through the data manager program and uploaded to the instrument.
