How to Use the 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.
