A: NIOSH recommends not exceeding the method-stated maximum flow rate. Instead, sample for a longer period and monitor closely for breakthrough. Use inert PTFE tubing to connect two tubes in series or for other applications in which the air sample comes into contact with the tubing before collection onto the sampling media.

SPIKES are 6 x 110-mm () glass-sealed sorbent tubes. Each tube contains two sections (300/1 mg) of high-purity (low-background) silica gel sorbent treated with,4-dinitrophenylhydrazine and glass wool separators (WWW). The 300-mg section is spiked with formaldehyde to ± 5% of the stated target level. Formaldehyde SPIKES are stocked at these commonly requested levels and are sold in packages of 10. Spike Level Cat.
