• Description:
  Decisions regarding the selection of chemical protective gloves are often based on general permeation guidelines. The major assumption is that glove types are equivalent. The aim of this study was to characterize and compare nine types of powder-free, unlined, and unsupported nitrile gloves using attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectrometry to assess suitability for surface infrared analysis of the dicarboximide fungicide Captan. Within glove, between glove, and between lot variabilities were measured for 13 gloves from 5 manufacturers at 740, 1124, 1252, and 1735 cm-1, the characteristic Captan peak wavelengths. Appreciable glove reflectances will limit sensitivity. Relative humidity (RH) and temperature effects on the surfaces of three gloves were evaluated by preconditioning them overnight at 2 +/- 1, 31 +/- 1, 55 +/- 1, 76 +/- 2, and 87 +/- 4% RH. For all gloves except one (Best, inner), 1735 cm-1 provided the greatest sensitivity. At 1735 cm-1 outer glove absorbances ranged from 0.0074 +/- 0.0005 (Microflex) to 0.0195 +/- 0.0024 (Safeskin). Average within glove coefficients of variation (CVs) ranged from 2.7 (Best, range 0.9-5.3%) to 10% (Safeskin, 1.2-1.7%). Within glove CVs greater than 10% were for one brand (Safeskin). Between glove CVs ranged from 2.8 (Best) to 28% (Safeskin). Between lot variation was statistically significant (p<0.05) for all lots tested (Best, Microflex, and Safeskin). RH had variable effects dependent on brand and wavelengths. For two gloves (Ansell and Microflex), absorbances at 740 cm-1 and 3430 cm-1 (-OH stretching) increased significantly (P<0.05) with increasing RH. Overall, substantial within glove, between glove, and between lot variabilities were observed. ATR-FTIR is a rugged analytical tool for measuring glove surface reflectance, detecting surface humidity effects, and choosing selective and sensitive wavelengths for infrared analysis of nonvolatile surface contaminants.
