NEWS + EVENTS

SGS Galson has added Methods for the Determination of Hazardous Substances (MDHS) 14/4 to our scope of accreditation. MDHS consists of a series of books published by the Health and Safety Executive (HSE) of the United Kingdom.

MDHS 14/4 specifically discusses inhalable particulate collection and analysis using IOM samplers, which were designed by the Institute of Occupational Medicine in the UK. At SGS Galson, we do an increasing amount of inhalable dust analysis in gravimetric techniques and are beginning to send them to the EU for other projects.

HOW WILL YOU BENEFIT?
Our clients, especially in the UK and globally, who prefer HSE methods of Respirable, Thoracic and Inhalable Dust Analysis, will have a helpful method for testing. This methodology is becoming increasingly widespread in the US, so you now have a reliable method for MDHS 14/4, accredited and added to our online Sampling + Analysis Guide.

TECHNICAL INFORMATION
At SGS Galson, we’re performing inhalable dust analysis using method NIOSH 0500/MDHS14/4, using two to four replicate samples for each batch of field samples for quality assurance, and a gravimetric analytic technique.
