How to Detect Mercury, Arsenic, and Selenium in Environmental and Food Samples

P S Analytical (PSA) provides niche analytical instruments for the determination of mercury, arsenic, selenium, antimony and bismuth in many sample matrices including environmental and food and beverage samples.

The presence of these toxic metals in their various forms is of real concern. Increasingly the determination of both total and speciated chemical forms is required and this requirement generates further analytical challenges of sensitivity, selectivity and freedom for interferences. 

In addition to analytical considerations operation issues such as; ease of use, reliability and robustness as well as very affordable running costs are all important and are recognised hallmarks or the PSA brand.

Coupling Atomic Fluorescence Spectroscopy (AFS) with either cold vapour generation or hydride generation has been PSA’s core competency for over 30 years. With the addition of analyte separation capability which allows for speciation studies, PSA offers some powerful tools to help with these endeavours. 

For example, the separation of; methyl mercury from inorganic mercury in water, shellfish, seaweed, dairy products, vegetables and grains; the determination inorganic arsenic from less toxic organo arsenic species in water, rice, seaweed are examples of routine applications developed for this growing area of concern.

The team is constantly developing new methods and applications to address market concerns and so if you have a sample you are interested to know more about with, PSA would love to hear from you.

With literally thousands of systems in the field today, and support networks in Europe, USA and SE Asia, PSA offers the ideal package of performance, reliability and support.
