SKC 225-49 IFV Pro Sampler Instruction Manual

SKC 225-49 IFV Pro Sampler Instruction Manual

Description

The SKC IFV Pro Sampler collects mixed-phase (aerosol and vapor) contaminants simultaneously. The stainless steel sampling head with an IOM-style inhalable inlet holds a filter cassette with a recommended 25-mm filter to
collect the aerosol phase; the attached tube holder (rubber sleeve) holds the method-specified sorbent tube to collect the vapor phase. The sorbent tube is protected by an open-ended plastic cover (Figure 1). IFV Pro is used with a sample pump capable of maintaining a constant flow rate of 1 L/min.

Preparation and Assembly

Wear powder-free gloves when handling cassettes and use forceps when working with filters to prevent the transfer of moisture, dust, or other contaminants onto the sampling media.

Disassembling Sampling Head

1. Remove the white cap from the sampling head inlet and set it aside.
2. Unscrew and remove the front plate of the sampling head.
3. Remove the filter cassette.

Filter Cassette: Opening, Installing Filter, and Closing

Tip: Place cap on filter cassette inlet for better grasp when opening cassette

1. To open the cassette, twist the cassette top in the cassette bottom until the notch in the top (Figure 3) is aligned with one of the two bumps on the cassette bottom; tilt the notched side up and lift.
2. Using forceps, place a 25-mm filter on the support grid in the cassette bottom.
3. Align the notch in the cassette top with one of the two bumps on the cassette bottom and insert the opposite edge of the top under the opposite bump in the cassette bottom. Set the top into the bottom and twist to secure the cassette (Figure 3).

Transporting Loaded Cassettes If not ready to sample immediately or if transporting loaded cassettes to a sampling location, place the filter cassette (with cap in place on the inlet) in the transport container. Ensure that the foam insert is in the container lid (Figure 4).

Figure 4. Cassette in Transport Container

Installing Filter Cassette in Sampling Head

1. Ensure that the O-ring is positioned correctly in the top of the housing (Figure 2) and place the loaded filter cassette on top of the O-ring (Figure 5).
2. Replace the front plate on the housing and turn clockwise until tight. Tighten securely to achieve a good seal.
3. Install the cap on the inlet until ready to sample

Assembling Sorbent Tube and Cover with Sampling Head (Figure 6)

1. Unscrew the tube cover from the sampling head.
2. Install a new tube holder (rubber sleeve Cat. No. P3022A) on the sampling head outlet. Note: It is important to install a new tube holder before each new sampling operation.
3. Break the ends off the sorbent tube using a tube breaker.
4. Insert the opened sorbent tube into the tube holder on the sampling head base. Note: The arrow printed on the tube should be pointing away from the rubber sleeve and toward the pump.
5. Attach flexible tubing to the other end of the sorbent tube.
6. Insert the open end of the flexible tubing through the threaded end of the protective tube cover; slide the tube cover up and over the sorbent tube to the base of the sampling head.
7. Thread the tube cover onto the base and turn until snug

Calibration

Calibrate pump flow rate using a calibrator, calibration adapter, and a representative loaded sampling head and sorbent tube in line. See the calibration train in Figure 7.

1. Following best practice, ensure that the sample pump has run for 5 minutes after charging to ensure a more stable flow.
2. Remove the cap from the cassette inlet and set it aside.
3. Place the calibration adapter outlet on the sampling head inlet and press firmly.
4. Using flexible tubing, connect the calibration adapter inlet to a calibrator.
5. Attach flexible tubing from the sorbent tube to the sample pump inlet.
6. Calibrate the flow rate to 1 L/min. See pump and calibrator operating instructions.
7. Disconnect the calibrator and calibration adapter. Remove the representative filter cassette and sorbent tube. Note: Keep representative media to verify flow rate later.
   Figure 7. Calibration Train

Sampling

Note: Before each new sampling operation, install a new tube holder (rubber sleeve Cat. No. P3022A) on the sampling head outlet.

1. Ensure that representative sampling media has been replaced with fresh, unused media (designated filter and sorbent tube) and that the cassette cap has been removed and set aside.

2. Connect the flexible tubing from the sorbent tube to the pump inlet.

3. Clip the sampler onto the worker’s clothing in the breathing zone; clip the pump onto the worker’s belt or place it in a protective pouch (Figure 8).

4. Start the pump and sample for the time specified in the method being used. See pump operating instructions.

5. Stop the pump. Detach the flexible tubing from the pump inlet.

6. Remove the protective tube cover and flexible tubing from the sorbent tube.

7. Remove the sampling media. Seal the sorbent tube ends with the caps provided. Place the filter cassette, with cap on, in the transport container; place the foam insert in the lid (Figure 4).

8. Remove and dispose of the tube holder.

9. Record all pertinent information.

10. Package samples as appropriate for shipment to a laboratory for analysis. See Transporting Samples to a Laboratory.

Transporting Samples to a Laboratory

Filters
Place the cassette transport container in a plastic bag or suitable container. Package in a padded envelope along with pertinent sampling information and blanks. See Sample Blanks.

Sorbent Tubes
Pack the sample sorbent tubes, field (sample) blanks, and all pertinent information securely for shipment to a laboratory for analysis.

Sample Blanks
Load and handle the blank IFV Pro Sampler in the same way as the sampler used for sampling. Do not pull air through the blanks. For sorbent tubes, submit field blanks from the same lot as the sample tubes. Send blanks with samples to a laboratory.

Cleaning Sampling Head

1. Disassemble the sampling head (Figure 2). Ensure that the tube holder has been removed.
2. Place the front plate, housing, and filter cassette in an ultrasonic cleaner with water and a wetting agent such as mild soap. Components may also be cleaned with a solvent such as isopropyl alcohol. Clean the O-ring separately with water.
3. Wipe components using a clean, lint-free paper, cloth, or soft brush. Allow components to dry completely
