Respirable Alpha Quartz Analysis

X-ray Diffraction Respirable Alpha Quartz Analysis

Filters are analysed for respirable alpha quartz content by direct on X-ray Diffraction [XRD] according to Method MDHS 101, “Crystalline silica in respirable airborne dusts – Direct-on-filter analysis by infrared spectroscopy and X-ray diffraction”.

A state of the art Bruker D4 Endevour automated 64 loader X-Ray analyser is used to ensure fast turnaround times.

NIST SRM 1878a is used to prepare calibrations filters.

 

Infrared Spectroscopy Respirable Alpha Quartz Analysis

Alpha quartz content of filters is determined by preparing potassium bromide [KBr] pellets and analysing the pellets by Fourier Transform Infra-Red [FT-IR] spectroscopy according to NIOSH 7602, “Silica, crystalline by IR [KBr pellet]”.

BBE Laboratory analyses client prepared KBr pellets or can prepare, press and analyse pellets from supplied filters according to NIOSH 7602, “Silica, crystalline by IR [KBr pellet]”.  KBr pellets are pressed using an automated press to ensure quality and to speed up turn around time.

Direct-on-filter respirable alpha quartz content determination can also be conducted by FT-IR spectroscopy according to Method MDHS 101, “Crystalline silica in respirable airborne dusts – Direct-on-filter analysis by infrared spectroscopy and X-ray diffraction”.
