PRINCIPLE OF OPERATION

A sample pump draws air at a flow rate of 10 L/min through nozzles on top of the sampling head and into the media cartridge inside the cartridge holder section. The media cartridge contains a cleaned 47-mm quartz filter that collects particle and a cleaned PUF or PUF/XAD-2/PUF sorbent that adsorbs gases and vapors. See Figure 2. The aluminum foil-wrapped cartridge is supplied in an aluminum with lid so that the sample is protected from light and contamination during transport. The filter and sorbent media are combined for extraction followed by GC/MS or HRGC/HRMS depending on the method used.

SAMPLING HEAD PREPARATION

Cleaning the Sampling Head

All cleaning, loading, and unloading should be conducted in a controlled environment to minimize any chance of potential contamination. When new
or when using the sampler at a different location, all sample contact areas need to be cleaned. Rinse with appropriate organic solvent. Allow the solvent to evaporate before loading a cartridge.

For deployed applications where method-specified solvents are unavailable, use isopropyl (rubbing) alcohol or a clean tissue wipe.
Do not place any mechanical object in the inlet nozzles

O-ring Care for the Sampling Head

Visually inspect the condition of the BUNA-N exhaust O-ring. See Figure 2. Ensure the O-ring surface is smooth (i.e., without cracks, cuts, or other damage). Ensure the O-ring is fitted properly in its channel. Replace the exhaust O-ring if there is apparent damage, stretching, or thinning. It is
recommended that the PTFE inlet O-ring be replaced by the manufacturer only.

Inserting a Media Cartridge into the Sampling Head

Wear disposable, clean, lint-free nylon or powder-free surgical gloves to handle the media cartridge.

1. Disassemble sampling head. See Figure 2 for placement of parts.
   a. Unscrew inlet section from cartridge holder section.
   b. Unscrew cartridge holder section from exhaust sect Sampling Head.

2.  Thread cartridge holder section onto exhaust section.

3.  Remove media cartridge from aluminum foil and insert into cartridge holder section. Ensure airflow arrow on media cartridge points to exhaust section. The filter should be on the inlet side of the media cartridge.

4. Thread inlet section onto cartridge holder section until just tight. Further hand-tighten by 1/4 turn only.

SAMPLE PUMP OPERATION

The user may choose to:

•  Operate the pump manually in the field (on/off )
• Program a schedule into the pump manually
• Program the pump for multiple schedules from a PC
  with optional Data Trac® for Leland Legacy Software (see Ordering Information, Accessories).See the Leland Legacy Quick Guide to operate the SKC Leland Legacy Sample Pump. For advanced programming, seethe complete Leland Legacy Pump Operating Instructions.

Charging the Battery

Completely charge a new battery pack using the SKC-approved charger (Cat. No. 223-241) before operating the pump. It may be necessary to charge the battery a few times before maximum battery capacity is achieved.
Cautions:

•  Do not charge or operate pump with or without charger in hazardous locations.
• Use only the SKC-approved charger for this pump. Use of an unapproved charger may damage the battery and pump and VOIDS ANY WARRANTY.
•  Do not open, disassemble, short circuit, crush, incinerate, or expose the battery to fi re or temperatures in excess of 212 F (100 C).
•  Tampering with the battery pack VOIDS ANY WARRANTY.
•  Ensure proper orientation of charging cable before plugging it into the charging jack. Improper orientation/contact will short-circuit the batt eryand VOIDS ANY WARRANTY.
•  Short-circuiting the battery pack will render it immediately inoperative.
• Failure to follow warnings and cautions VOIDS ANY WARRANTY.

The battery pack may be kept on the SKC-approved charger for an indefinite time.
1. Insert the plug from the charging unit into the charging port on the battery adapter (on top of the external battery assembly).
2. Insert plug from power supply into the jack on the charging unit.
3. Install the appropriate wall plug on the power supply and plug power supply into a wall outlet.

The battery will recharge in approximately 15
hours. For a complete charge, do not run the pump connected to the external battery assembly during charging. After charging is complete, disconnect
battery from charger and connect pump to battery.
See Battery Setup.

After charging the battery pack, it is good practice to run the pump for approximately 5 minutes before calibrating. This ensures the battery is
in more steady-state conditions and improves the agreement in pre and post- sampling calibrations.

Reading the Charging Status LED

The Li-Ion Charging Unit indicates battery charge status via an LED on the unit that blinks in specific patterns. Observe the LED steadily for > 5 seconds to read charge status.

CALIBRATION AND SAMPLING

Calibration

Calibrate pump flow rate with the sampling head loaded with a media cartridge in line. See pump and calibrator operating instructions. Allow the pump to equilibrate after moving it from one temperature extreme to another. Wear disposable, clean, lint-free nylon or powder-free surgical gloves to handle the media catridge.

(1) Ensure pump has run for 5 minutes before calibrating. Ensure rain cover is removed from inlet and that sampling head is completely assembled with a media cartridge (see Inserting a Media Cartridge into the Sampling Head).

Thread calibration adapter into sampling head inlet.

Unscrew quick-connect plug on side of case. Use tubing with quick-connect fitting to attach case (pump) inlet to exhaust of sampling head.
Ensure O-ring is installed on the quick-connect fitting before inserting it into the inlet. Absence of the O-ring can affect measurements. See Replacement Parts

Use provided short length of calibration tubing to connect inlet of calibration adapter to outlet of a calibrator to form a calibration train. Note: SKC High Flow check-mate Calibrator requires Pulsation Dampener Cat. No. 375-150 in line as shown at above right and in Step 5 (see Accessories).

Set and calibrate pump flow rate to 10 L/min (see Leland Legacy Quick Guide). Record the pre-sample flow rate. See pump and calibrator operating instructions

When calibration is completed, disconnect calibrator and tubing from calibration adapter. Remove calibration adapter from sampling head.

Sampling

Locate system in an unobstructed area, at least 6 feet (2 meters) from any obstacle to airflow.
Allow pump to equilibrate after moving it from one temperature extreme to another

1.  Attach mounting bracket at the desired location and at breathing zone height (6 feet or 2 meters) using wire ties or other fasteners. Mount sampling head loaded with media cartridge on mounting bracket by threading clamp knob into bott om of sampling head.

2.  Insert screw on rain cover into top of the sampling head inlet and rotate cover until tight.

3. Turn on pump and record sample start time, ambient temperature, ambient pressure, and other pertinent
   data.
   Sample start time and duration can be programmed into the Leland Legacy Sample Pump in advance and sampling may be started manually or automatically.
   Record all necessary data before disconnecting pump from battery and reconnecting to new.

4. After desired sample time has elapsed, record sample stop time. Remove rain cover from sampling head and reinstate calibration adapter, tubing, and calibrator (see Calibration). Record post-sample flow rate.

5. Turn off pump. Record total volume, ambient temperature, ambient pressure, and other pertinent data.

6. Reach inside case and press quick-connect release while pulling tubing from case (pump) inlet. Remove tubing from sampling head. Remove sampling head from bracket.
