Detecting mercury, arsenic and selenium in environmental and food samples
PS 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, they 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.

Anton Paar offers two exceptional spectroscopy instruments: the Lyza 7000 FTIR Spectrometer and the Cora 5001 Raman Spectrometer. This guide highlights the distinct advantages of each to help you choose the best fit for your needs.
FTIR spectroscopy is the favoured method for identifying organic and some inorganic materials by measuring their absorption of infrared light at different wavelengths. It’s ideal for comprehensive material verification and quality control.
Anton Paar’s Lyza 7000 leverages cutting-edge FTIR technology, providing precision and versatility for analysing solids, liquids, and gases.
Key features include: Guided workflows: Intuitive touchscreen and embedded software; Rapid and reliable measurements: Ideal for quality control; Robust design: Durable with a hermetically-sealed aluminum optics compartment and cube corner interferometer.
Raman spectroscopy is suited for minimal sample interaction where clear substance characterisation is required without altering the sample state.
Anton Paar’s Cora 5001 is a state-of-the-art benchtop Raman spectrometer known for its precision and ease of use. Raman spectroscopy identifies chemical compounds without the need for any sample preparation.
Key features include: Autofocus: The unique autofocus guarantees precision and ease of use; Minimal sample preparation: Allows direct analysis through glass or plastic containers, ideal for rapid substance identification; Sampling accessories: Regardless of whether the sample is a solid, liquid, or powder, Cora 5001 has the appropriate sample holder for it.
Choosing the right spectrometer
FTIR is highly recommended for comprehensive analytical tasks that require detailed information and quality control for a wide array of sample types, including deeply-coloured and fluorescent samples. For many samples, established SOPs (e.g. ASTM standards) for IR spectroscopy are available.
Raman is best suited for rapid, non-invasive testing and precise substance identification, particularly in pharmaceutical and forensic settings. Samples can be measured through packaging, allowing the measurement of air- and moisture-sensitive materials. Cora 5001 includes a battery option for analysis directly in the field.
Anton Paar’s Spectroscopy Suite integrates with both Lyza 7000 and Cora 5001, providing solutions tailored for regulated environments.
Key benefits include: Efficiency: Predefined workflows speed up measurements and prevent errors; Compliance: Adheres to 21 CFR Part 11 and EU GMP Annex 11; Data integrity and management: Ensures lifetime data integrity with versioned methods, secure electronic signing, active directory, and comprehensive data management.
