and Air Sampling System User Manual

PRODUCT OVERVIEW

AirPrep™ Cub Sampler ACD210 model has an internal battery
AirPrep™ Cub Sampler ACD220 model is plug-in only
1.1 PRODUCT DESCRIPTION
The AirPrep Cub Sampler is a dry filter air sampler that operates using InnovaPrep’s unique, patented rapid filter elution products to provide samples for a wide range of indoor and outdoor biomonitoring applications.
1.2 COLLECTION CAPABILITY
The AirPrep Cub Sampler is suited for the collection of bioaerosols (bacteria, molds, and viruses) and other particulate matter, including sub-micron sized particles, and airborne molecular contamination. The AirPrep Cub Sampler efficiently captures micron- and submicron-sized particles, including viruses, bacteria, pollen, molds and fungal spores, as well as non-biological particles from 0.01 micron to 10+ microns.

Users can select from three flowrate modes: 50 LPM, 100 LPM, or 200 LPM from the front panel as described in Section 4.
Users can select from four timed modes: 30 minutes, 1 hour, 2 hours, or continuous from the front panel as described in Section 4.
Expected continuous run times for ACD210 battery: 50LPM – 16hrs, 100LPM – 8hrs, 200LPM – 4hrs
Since liquids are not used in the collector, the system can be operated in extreme temperatures (see specifications in Section 6).

METHOD OF OPERATION

The AirPrep Cub Sampler uses an electret filter to capture particles. To recover the trapped particles, a novel Wet Foam Elution™ process is employed to break the electrostatic charge and flush the particles off the filter into a small liquid volume in seconds.
2.1 SAMPLE COLLECTION ON AN ELECTRET FILTER
The dry 52 mm electret filters are made with a combination of positively charged and negatively charged fibers. This substantially increases the collection efficiency of the filter and allows for the use of lower pressure drop filters, which, in turn, allows for higher sampling rates for extended periods using battery power.
2.2 INSTANT WET FOAM ELUTION™
The patented wet foam elution process uses a very specific high-quality foam to elute the filter. The elution buffer is composed of water, a low concentration surfactant (0.15% Tween 20), and a pH buffer (Tris or PBS). This solution is carbonated, which dissolves significant amount of CO2 into the fluid. During the elution process, the valve opens as the elution canister is pushed into the elutor adapter that is fitted onto the filter, forcing the elution buffer through the pressure orifice, through the filter and into the sample cup. As the fluid passes from the high-pressure environment on one side of the orifice, to the low-pressure environment on the other side, the dissolved CO2 expands, comes out of the solution to form micro-bubbles. These micro-bubbles increase the volume of the fluid six-fold or more as it passes through the filter. The foam immediately collapses back into a liquid and is ready for sample processing and analysis. InnovaPrep’s patented Wet Foam Elution process ( https://www.innovaprep.com/patents ) is much more efficient than liquid rinsing for the following reasons:

Volume Expansion – When rinsing a filter with liquid, most of the liquid volume is used to fill the dead space inside the filter housing; only a small portion of the fluid covers the filter surface. This can be avoided to an extent by reducing the cross-sectional area of the fluid path across the filter, but a large portion of the liquid is still underutilized. Because our elution buffer is 80-90% gas, this fills the empty space without contributing to the final sample volume.
Increased Viscosity – Liquid has a tendency toward “channeling” when flowing through a filter, creating an area of high flow in the center of the fluid path, while the portion of flow in contact with the filter surface is much slower. The higher viscosity of our elution buffer as a foam prevents channeling and allows for a more uniform flow through the interstitial spaces of the filter.
Bubble Dynamics – The micro-bubbles in the foam behave as deformable solids. As they travel through the filter they move as a rigid body.
Exfoliating Action – As the micro-bubbles in the foam impact against each other and burst, the turbulence and energy produced helps to lift particles that are adhering to the filter fibers.
Buffered Elution – The buffered elution fluid is conductive and breaks down the electrostatic charges holding the particles to the electret filter, effectively releasing them in the liquid sample.

PROCEDURES

This section includes some of the basic instructions for operation.
4.1 SETTING UP THE AIRPREP CUB SAMPLER FOR COLLECTION
Push the barrel plug of the power supply (Figure 2) into the power jack on the bottom of the instrument. Plug the AC Power Cord into the power supply and plug the other end into an appropriate wall outlet.

4.2 INSTALLING THE FILTER
Open the inlet cap by twisting it to the left to lift off. Insert the filter into the top of the AirPrep Cub Sampler, as shown in figure 2. The filter housing is designed to only fit in one way. Screw the inlet lid on (twisting right) to close.
4.3 CONTROL PANEL INTRODUCTION
The control panel consists of four timer setting LED indicator lights, three flowrate LED indicator lights, and one momentary pushbutton switch (Hold/Mode).
Two variables constitute a “run mode”: flowrate and runtime.
To turn on and off:

Press Hold/Mode for 2 seconds to Power on/power off

To change run modes

press the Hold/Mode for 4 seconds

Reset Button

A reset button is located on the bottom of each instrument, pressing this will result in an immediate system interrupt and reset of the system.

4.3.1 LED INDICATOR LIGHT
The Battery LED Indicator Light (Model 210 only) will flash in the following situations:

When a run mode is selected that exceeds the expected battery capacity
After the battery is drained low enough to shut down the fan before the timer expired
The battery LED indicator light will start to flash slowly as the charge approaches a critical level- increasing in frequency until it is steady on when the battery is at its preset critical charge.

The battery LED indicator will turn solid if the power supply is plugged in and the system is charging. It will shut off when it is fully charged.
Battery Status Indicator
By holding the power button for 2 seconds, then release, the Power LED will light up solid, followed by a combination of the five green LEDs on the left side of the panel. Each green LED that is lit indicates 20% of the battery. Example: If 3 of the 5 green LEDs are lit this would indicate approximately a 60% battery charge.

Flowrate LED Indicator Light
The flowrate LED indicator for the selected run mode will stay on while the fan is running.
Timer LED Indicator Light

The timer LED Indicator light will flash slowly as they countdown, as they approach the expiration they will increase in frequency until the unit times out and shuts down. The light will remain solid for the last 10% of the timer.
If the timer is set to continuous, the LED indicator light will stay steadily on.

4.3.2 POWER ON
When powering-on the sampler, the previous run mode will be recalled and started by default.

4.3.3 POWERING OFF MANUALLY BEFORE TIME EXPIRES

If a time & flowrate combination requires more battery than is available, the battery LED will flash to alert you
4.4 RECOVERY OF THE SAMPLE

When the run is completed, recover the filter from the sampler with gloved hands by twisting the inlet to the left to open.
Remove the filter cassette, invert it top-side-down, and press onto the sample cup firmly until it clicks all the way around the cup. Perform this on a stable surface.
Cap the filter with the elutor adapter as shown in Figure 6 (make sure the filter and elutor adapter are fully sealed).
Place the filter assembly in a zip-type bag for transporting dry, or alternatively, elute the filter as described in the following section.

4.5 ELUTING THE SAMPLE FROM THE FILTER
To extract the captured particles from the filter:

Place the sample cup, filter, and elutor adapter, as shown in Figure 6, on a stable surface.
Firmly press the elution buffer canister into the elutor adapter. The elution buffer will be released as a foam from the canister through the filter when the canister valve is pressed down. Hold the canister down until all the foam is released. The foam quickly collapses into a liquid in the sample cup and available for sample processing and analysis.

4.6 CLEANING THE SAMPLER
Common off-the-shelf alcohol or bleach wipes can be used for cleaning and disinfection of the entire sampler. If applicable, disconnect the AC power plug prior to cleaning.
