IH Sampling Best Practices

IH Sampling Best Practices
Competent sample collection requires frequent observations of conditions and operations that could impact the sample results. Document major work activities during sample collection. Field notes should be detailed enough to be able to provide an explanation of the sample results, uncover any issues with sample tampering, or any other issues that arose during sample collection.

Field blanks are required for all sampling activities. Field blanks are used by the lab to determine if contamination has occurred before analysis or during sample handling, shipping, or storage. Field blanks (e.g., sorbet tubes, filters, absorbing solution) are clean sample media that are taken and opened in a clean area at the sampling site, but they are not used to take samples. They should be handled, stored and shipped in the same manner as other sampling media used in sampling air contaminants, with the exception that no air is drawn through them. Field blanks are required for each requested analysis and for each lot number of sampling media. Prepare field blanks during the sampling period for each type of sample collected. One field blank will usually suffice for up to 20 samples for any given analysis/sampling period.

FLOW RATE: ~2.5 L/min w/Aluminum Cyclone
VOLUME: 100 to 960Liters
BLANKS: One blank per set of samples
SPECIAL INSTRUCTIONS: Ensure grit pot is present on the cyclone, an absent grit pot permits massive leakage and prevents proper sample collection.
Never invert cyclone separator during or after sample collection, this will cause erroneous high results.
PRIOR TO SAMPLING: Clean all parts of the cyclone, including the interior of the grit
pot, with mild soapy water. The cyclone may be wiped with a clean dust-free tissue, air
dried, blown dry, or wiped with isopropyl alcohol.
