ChemWipes Surface Contamination analysis. Chemteq ChemWipes are surface wipes for the detection and quantification of chemicals on surfaces.

  • Selective and sensitive.
  • Because of the uniform color change on the wipe, user can determine the concentration of  chemical on the surface using the color comparator.
  • The ChemWipe is 0.33” thick, 1.25” diameter.
  • Shelf life of at least 12 months at room temperature
  • The ChemWipes are available for:
    1. Aromatic diisocyanates., toluene 2,4-diisocyanate (2,4-TDI), toluene 2,6-diisocyanate (2,6-TDI) and 4,4′- methylene diphenyl diisocyanate (MDI).
    2. Mercury and mercury II compounds
    3. Nickel II compounds..

Surface Contamination Regulations
The current Occupational Safety and Health Administration (OSHA) standards have no surface contamination standards or determination for surface contamination.
The standards generally contain housekeeping conditions that address the issue of surface pollution. Exposures to different chemicals are addressed in specific standards for general industry, construction, and shipyard employment.

OSHA housekeeping requirements are generally the most strict for the metals. In solid form, metals may contaminate surfaces. It become available for consumption or inhalation if housekeeping practices are poor. OSHA standards for heavy metals contain requirements stating “surfaces be maintained as free as practicable of accumulations of toxic metal”. [Code of Federal Regulations (CFR) for Occupational Safety and Health Standards 29 CFR 1910].
United States Department of Energy (DOE) provides useful guidelines.  DOE and its contractors required to conduct routine surface sampling to determine housekeeping conditions wherever highly toxic and carcinogenic substances. Metals such as beryllium and hexavalent chromium [Cr (VI)] are present in operational areas. These measures, for example, state that for beryllium, the removable contamination level of equipment or item surfaces does not exceed the higher of 0.2µg/100 cm2. For Cr (VI), an acceptable surface contamination level of 7.5µg/100 cm2.

ChemWipes Surface Contamination Testing

The Chemteq ChemWipes are surface contamination testing and quantification wipes. The uniform color change can be quantified by the color comparator

ChemWipes are surface contamination testing and quantification wipes. The unique design of the ChemWipe provides uniform color change formation enabling user to quantify chemical contamination using the color comparator.

Available ChemWipes:

  1. Aromatic diisocyanates
  2. Mercury and mercury II compounds
  3. Nickel II compounds.
