treated with mercuric chloride loaded into a three-piece 37-mm casse e in closed-face sampling confi guration
Prior to Sampling: Store at 39.2 F (4 C) for up to 3 months.
Sample Stability: Store samples at 39.2 F (4 C) or 71.6 F (22 C) for up to
17 days.

How to Use SKC Preloaded Coated Filters
1. Select one coated fi lter casse e for calibrating the fl ow 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 fi lter casse e in line. For “closed-face” sampling, remove the plugs and connect the casse e to the sampling train. For “open-face” sampling, remove the outlet plug and the casse e inlet section then connect the casse e to the sampling train. For details on se ing up a sampling train, refer to the SKC Sample Setup Guide “Sampling Train - Filters and Cyclones” (SKC Publication 1166).
2. Calibrate the pump to the desired fl ow rate using a fi lm fl owmeter or calibrated precision rotameter. For details on calibrating a pump, refer to the SKC Sample Setup Guide “Calibrating a Pump Using a Film Flowmeter” (SKC Publication 1163).
3. Replace the casse e used for calibration with a fresh coated fi lter casse e for sample collection. A ach the casse e to a worker’s collar, as close to the breathing zone as possible, by using a fi lter casse e holder (SKC Cat. No. 225-1). Sample for the specifi ed time interval and record the time.
4. Remove the fi lter casse e at the end of the specifi ed sampling period and replace both end plugs (and the inlet if necessary). Recheck the fl ow rate using the same casse e and fl owmeter used for calibration in Step 2 to ensure that the fl ow rate has not changed by more than 5%.
5. See Sample Stability on reverse side for sample storage. Appropriately package samples, blanks, and all pertinent data to send to a lab for analysis. Expedite shipping of samples to laboratory. Friday shipments are not recommended.
