14 Determining the Elemental Content in Sewage Sludge
Operators of wastewater treatment plants need reliable data to identify the elemental content in the sludge and assess its recycling potential. With the PlasmaQuant 9100, Analytik Jena offers a suitable measuring instrument for this purpose. With this multi-element analyser, elements can be determined precisely and rapidly.
Phosphorus recovery is also a legal issue. Classified as a critical raw material by the European Commission, the German Sewage Sludge Ordinance (AbfKlärV) makes recovery mandatory starting January 2029. Wastewater treatment plant operators must - depending on the size of their municipal discharge area - gradually implement phosphorus recovery from sewage sludge or its incineration ash if the phosphorus content exceeds 20 grams or more per kilogram of dry matter.
However, sewage sludge also contains heavy metals and other pollutants that must not be released into the environment. In addition, sewage sludge yields are high matrix samples. They contain a very wide range of elements in very different concentrations, as well as high proportions of salt compounds. This presents a challenge for high-throughput measurement.
The PlasmaQuant 9100 uses the principle of inductively coupled plasma optical emission spectrometry (ICP-OES). Samples are atomised, activated, and then ionised over 5,000-10,000 Kelvin argon plasma. A spectrometer measures the emitted electromagnetic radiation. The resulting signal intensities provide information about the concentration of the contained elements. The application is described in the EPA methods 3050B and 6010C, as well as in the standards DIN EN 16174:2012-11 and ISO 11885:2007.
High measurement sensitivity is particularly relevant for the critical elements (e.g., cadmium, mercury, and thallium), as strict limits apply to their release into the environment. The DualView Plus feature of the PlasmaQuant 9100 extends the linear dynamic range and greatly simplifies multi-element analysis by allowing the entire element screening to be performed simultaneously in one measurement run through different plasma observation modes, while maintaining the best possible detection strength for critical elements.
The entire analysis process becomes faster, more reliable, and more economical. Since the PlasmaQuant 9100 is characterised by very stable plasma, high-matrix samples can be measured with long- term stability also at high throughput. Also, sample dilution becomes obsolete.

Benchtop Tandem Quadrupole Mass Spectrometer
Waters’ Xevo™ TQ Absolute high-performance mass spectrometer is up to 15X more sensitive for quantifying negatively ionising compounds than its predecessor and is 45% smaller and uses up to 50% less electricity and gas supply than other high-performance tandem quadrupole mass spectrometers available on the market. The Xevo TQ Absolute is designed to help pharmaceutical, food and beverage, and environmental analytical laboratories meet regulations requiring trace-level quantitative mass spectrometry analyses for a broad set of applications.
For optimal performance, Waters pairs the Xevo TQ Absolute mass spectrometer with Waters’ ACQUITY™ Premier UPLC System with MaxPeak™ HPS technology which eliminates non-specific adsorption of compounds containing phosphate and/or carboxylate groups and improves their recovery.
Together, this integrated LC-MS/MS system is designed to drive the limits of quantitation to exceptionally low levels for many applications including: quantifying regulated impurities in drug products; performing oligonucleotide bioanalytical assays; measuring concentrations of endogenous metabolites in large cohort clinical studies; quantifying residues and contaminants in food and environmental samples; measuring low-level drugs and toxicants in physiological matrices; detecting trace-level leachables from food packaging.
The Xevo TQ Absolute incorporates thoughtful design features that enable consistent and reproducible analyses, allowing labs to maintain performance and uptime for longer periods in between routine cleaning and service intervals. This is achieved with new guidance on optimal probe positioning for both sensitivity and robustness and a source shield that helps minimise source contamination by the sample matrix or mobile phase salts.
The Xevo TQ Absolute is optimised for use with the waters_connect™ software platform and is also compatible with Waters MassLynx™ mass spectrometry software. For laboratories painstakingly reviewing the results from large numbers of samples, or those quantifying hundreds of small molecule components and contaminants in a single run, the MS Quan app on waters_connect and its unique Exception Focused Review (XFR) functionality, lets scientists review data in up to half the time it used to take them.

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:

Strategic Partnership Aims to Advance Proteomics CRO Services
Bruker Corporation and Switzerland-based Biognosys AG have announced a strategic partnership, in which Bruker has made a majority-ownership investment in Biognosys. Co-Founder and CEO Dr Oliver Rinner and his leadership team will continue to manage Biognosys as a world-leading proteomics and proteogenomics CRO services and proteomics software company. Going forward, Biognosys’ biomarker and biopharma customers will benefit from additional services and footprint in the US. Biognosys will access Bruker’s leading 4D proteomics timsTOF technology for deeper, unbiased high-precision proteomics that is not impaired by epitope cross-reactivity - all with higher throughput and excellent reproducibility.
Biognosys mass spectrometry-based proteomics solutions help CRO services and proteomics software customers in uncovering connections between genome, transcriptome, and phenotype to explore the static and dynamic nature of disease biology. In particular, the Biognosys TrueTarget™, TrueDiscovery™, and TrueSignature™ research service solutions provide deep, peptide-level proteome insights for drug discovery and development:
The Bruker-Biognosys collaboration is expected to create unique synergies between Biognosys’ versatile portfolio of proprietary proteomics services, software and kits, and Bruker’s pioneering timsTOF platform. As a result of the strategic partnership, Biognosys plans to open its first advanced proteomics CRO services laboratory in the United States.
