Interferences:* • Highly specifi c for formaldehyde. Large amounts of
carbonyl compounds may reduce the uptake of formaldehyde
• Use in ozone levels less than 0.5 ppm

Sampling Instructions
Cautions: • Store at freezer temperatures (≤ 39.2 F [4 C]) before use.
• Do not store with food.
• SKC recommends using gloves when handling chemically
treated media.
• Before sampling, check the expiration date on the pouch label.
Do not use a er the last day of the month indicated.
• UME
x
samplers are designed for single use only. Do NOT reuse
UME
x
samplers.
• Do not use Sharpie
®
markers or equivalent to mark label or
pouch as these can off -gas VOCs.
