Form 40036 Rev 211118 How to Use SKC Preloaded Coated Filters Ensure that filter cassettes are at room temperature before sampling. 1. 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 "openface" 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. 2. Calibrate the pump to the desired flow rate using a calibrator. 3. Replace the cassette used for calibration with a fresh 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. 4. 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%. 5. Store samples at 39.2 F (4 C) for up to 15 days. Appropriately package samples, blanks, and all pertinent data to send to a laboratory for analysis. Expedite shipping of samples to laboratory.
