The 581 is our fastest sampling rate aldehyde badge. Our traditional aldehyde collection media used in our 571 badge was inserted into the TraceAir® II configuration to allow for lower reporting limits. This monitor was designed for STEL monitoring for Glutaraldehyde, but can be used for Formaldehyde, ortho-Phthalaldehyde, and other Aldehydes.

Description

Assay Technology’s 581 Aldehyde Monitor is our fastest sampling rate, lowest reporting limit aldehyde badge.

Glutaraldehyde and ortho-Phthalaldehyde STEL

The badge was designed for Glutaraldehyde and 0rtho-Phthalaldehyde STEL monitoring.

Chemical 15 minute Reporting Limit, mg/m3  15 minute Reporting Limit, ppm
Glutaraldehyde 0.0084 0.0021
ortho-Phthalaldehyde 0.0093 0.0017

ACGIH STEL for OPA

Using the 581 badge, the 15 minute reporting limit for OPA  is 0.0093 mg/m3.  The ACGIH STEL for OPA is well below that at 0.0006 mg/m3.  To reach the ACGIH limit, monitor for at least 260 minutes and the reporting limit is 0.00054 mg/m3.

Formaldehyde

The 581 monitor can be used formaldehyde and the reporting limit will be lower than the 571 badge. However, the 571 badge is still the badge Assay Technology recommends for formaldehyde monitoring because the cost is less.  

However, customers that are going to use the NIOSH REL to evaluate their formaldehyde results should use the 581 badge, not the 571.  The NIOSH REL is 0.016 ppm, which is over 40 times below the OSHA PEL of 0.75 ppm.  Because of this, the faster-sampling 581 with an 8-hour reporting limit of 0.0014 ppm is preferred.

 

This badge collects the following:

  • Formaldehyde (formalin)
  • Glutaraldehyde (Cidex)
  • o-Phthalaldehyde (Cidex OPA)
  • Acetaldehyde
  • Benzaldehyde
  • Butyraldehyde
  • Crotonaldehyde
  • Hexaldehyde
  • Propionaldehyde
  • Tolualdehyde
  • Valeraldehyde

Special Notes

o-Phthalaldehyde (OPA) can not be tested with other aldehydes on the same sampler.
