59 Food & Beverage Analysis 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. More information online:

Elemental Microanalysis, a leading global supplier to the elemental analysis market, manufactures a product which continues to be useful in the market after 25 years.
The simple explanation of what the evaporating cup does, ‘drying liquid samples down to residues prior to feeding into an elemental analyser’, belies the amount of product engineering that went into designing a shape where the residue forms in the bottom
of the cup while also allowing easy folding. That explanation also does not highlight the extremely stringent quality control measures which make Elemental’s evaporating cups the leading choice among malting companies.
It started 25 years ago when Elemental was approached by a world-renowned Irish brewery which intended to specify a new, unique encapsulation product for drying their maltings sludge. They were working with an OEM on developing a robust, lightweight product with signifi cant fl uid capacity and dual laboratory use capability. The specifi c parameters of the encapsulation product included:
• 5ml liquid capacity • Compatible with hotplate evaporator • Easy to fold whilst containing dry residue • Lightweight • Suitable for combustion analysis

In collaboration with the brewery and the OEM, the design team at Elemental expended every effort to produce a tin foil evaporating cup that met the customer’s exacting requirements. Elemental’s team researched, designed, tested, developed, tested, further developed, checked, and tested again to product an appropriate product. Additionally, once the product was perfected, Elemental’s team developed unique packaging to ensure safe product transit for the delicate evaporating cups.
Today, Elemental Microanalysis’s ISO9001 accredited quality system continues to ensure that these evaporating cups - and all other analysis consumables - are of excellent quality at a competitive price. And malting companies across the globe have benefi tted from the humble beginnings of the now indispensable evaporating cups.
