Product: ISO-CHEK

Simultaneous and Separate Collection of Isocyanate Phases

 

  • Accurately samples diisocyanates: HDI, MDI, IPDI, HMDI, 2,4-TDI, and 2,6-TDI
  • The only filter-based system that simultaneously traps and separates both monomers and oligomers
    - For better determinations of control strategies
  • Decreases sample preparation and analysis time by 40% compared to other methods
    - Pre-made calibration standards are available
  • Highly stable — minimizes storage and handling
  • Highly sensitive analysis provides detection limits below current regulated exposure levels
    - Ideal for occupational sampling and environmental surveys
    - Requires only a 15-minute sample time
  • Meets the specifications of several methods
    - ASTM D5932 for 2,4 and 2,6-TDI
    - ASTM D6561 for HDI
    - ASTM D6562 for HDI
  • Round-robin proficiency testing for ISO-CHEK labs ensures accurate, consistent analysis
    - See laboratory list at www.skcinc.com

 

Suitable for most isocyanates, the patented# ISO-CHEK® filter cassette employs a two-stage filter arrangement that results in the simultaneous collection and separation of vapor from aerosol at the point of collection. The filter that collects the vapor phase is treated with 9-(N-methyl-aminomethyl) anthracene (MAMA), a highly stable reagent that minimizes storage and handling requirements.

ABOUT

ISO-CHEK Developement

ISO-CHEK was developed and patented by IRSST (Institut de recherche Robert-Sauvé en santé et en sécurité du travail du Québec).

 

the ISO-CHEK Advatages

Simultaneous collection and separation of phases at the point of collection; Less time-consuming and more accurate analysis of each phase

Reagent is stable at room temperature.

15-minute sampling time Provides results that are more meaningful than those from the longer sampling times required by other methods

No handling precautions No broken glass or splashing impinger liquid
