How to Use SKC Preloaded Coated Filters
**** Ensure that the filter cassette is at room temperature before sampling.
- Select one coated filter cassette for calibrating the flow rate. A red plug secures the inlet, which is clearly marked “inlet,” and a blue plug secures the outlet. Set up the sampling train for calibration with the representative filter cassette in line. For “closed-face” sampling, remove the plugs and connect the cassette to the sampling train. For “open face” sampling, remove the outlet plug and the cassette inlet section and then connect the cassette to the sampling train. For details on setting up a sampling train, refer to the SKC Sample Setup Guide “Sampling Train Filters” at www.skcinc.com/knowledgecenter.
- Calibrate the pump to the desired flow rate using a calibrator.
- Replace the cassette used for calibration with a freshly coated filter cassette for sample collection. Attach the cassette to a worker’s collar, as close to the breathing zone as possible, by using a filter cassette holder SKC Cat. No. 225-1. Sample for the specified time interval and record the time.
- Remove the filter cassette at the end of the specified sampling period and replace both end plugs (and the inlet if necessary). Recheck the flow rate using the same cassette and calibrator used for calibration in Step 2 to ensure that the flow rate has not changed by more than 5%.
- Store samples at 71.6 F (22 C) for up to 30 days. Appropriately package samples, blanks, and all pertinent data to send to a lab for analysis. Ship samples via next-day air to arrive at the lab on the following business day. Friday shipments are not recommended.
