Alex Stewart International [ASi] has commissioned a new modernised fire assay laboratory at its head office laboratory site in Liverpool, Merseyside.

Although fire assay is an ancient technique, it is still considered the standard method for determining the gold content in a range of precious metal bearing materials. This method has, however, also been supplemented by the use of modern-day instrumentation and the continuous advancement in technologies, which have improved the efficiency and accuracy of the precious metals assaying process. 

Reflecting these ongoing developments, ASi has continued to invest in its precious metal testing facilities and has commissioned a new modernised fire assay laboratory at its UK base.

Investments include the installation of state-of-the-art multi-pour fire assay furnaces, which have resulted in significantly increased assaying capacity. These furnaces are used in the initial fusion stage of the gold assaying process and are an integral part of the company’s fire assay laboratory.

As part of the investment, ASi have also modernised their ICP-OES laboratory with hi-tech equipment. Along with the upgrade to the furnaces, these investments have increased assaying capabilities significantly and will help to ensure swift result turn-around times and the high-quality accurate analysis which is expected within the industry.

To coincide with the commissioning of the new fire assay laboratory, a new video walkthrough of the fire assaying process was filmed at ASi’s Head Laboratories in Liverpool, which can now be viewed online here

Alex Stewart International [ASi] is dedicated to helping clients obtain the correct valuation for their precious metal materials. This is achieved through the provision of internationally accredited inspection, sampling and analytical services.
