19 Environmental Analysis & Electrochemistry 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.

Bluephage SL, a leader in microbiological water testing, has introduced two innovative product lines to enhance laboratory efficiency and water quality testing standards. These additions reinforce Bluephage’s commitment to delivering advanced, customer-centric solutions for water analysis worldwide.
The company has updated its Positive Control Kits, now available in two specialised formats: BP1626a and BP1626b. These kits, designed for coliphage enumeration, now contain 25 units per box - five more than the previous version - offering better value and flexibility. Laboratories can now purchase these controls separately, optimising inventory management.
The BP1626a kit is tailored for use with the Easy Kit BP1601 (1 ml samples), while BP1626b is optimised for the Easy Kit BP1604 (100 ml samples). Positive controls play a crucial role in ensuring accuracy and reliability in coliphage testing by introducing a known quantity of the φX174 bacteriophage, a global reference for detecting somatic coliphages. These kits comply with ISO 10705-2, the international standard for coliphage enumeration.
Bluephage is also launching GR8FHDT and GR8FHD, filterable formats of the GR8 somatic coliphage, designed to validate bacteriophage concentration in water testing. These products are compatible with Bluephage’s Rapid Kits (BPF-SE, BPF-SPA) and Easy Kits (BP1601, BP1604) and comply with ISO 10705-3, the key standard for bacteriophage concentration.
Bacteriophages often occur in low concentrations in water samples, making concentration methods essential for accurate detection. GR8, isolated from surface water, is an effective surrogate for environmental testing. Its filterable format simplifies laboratory workflows while ensuring adherence to global water safety standards.
With two-year shelf lives and storage at -20°C (GR8FHDT) or -70°C (GR8FHD), these new formats provide long-term, reliable solutions for laboratories.
These new product launches highlight Bluephage’s dedication to innovation, regulatory compliance, and laboratory efficiency in water quality testing.
