Viscosity testing for pharma and food: One instrument, fully compliant


Pharmaceutical producers, research laboratories, and manufacturers of food- grade materials rely on precise viscosity data to ensure specifi cation compliance. Anton Paar’s SVM series provides a fully compliant alternative to manual or automated capillary viscometers for Newtonian samples, covering pharmaceutical raw materials such as white oils and excipients, cosmetic oils, as well as food-grade products, including edible oils.

Pharmacopeias including USP and Ph. Eur. permit alternative viscometers when accuracy and precision are equivalent or better than established methods or when the alternative offers advantages in automation or data integrity. SVM fulfi lls these criteria and delivers dynamic and kinematic viscosity (ASTM D7042), density (ASTM D4052), and viscosity index (ASTM D2270) in one measurement. In combination with Abbemat refractometers, additional parameters – refractive index (ASTM D1218), molecular weight (ASTM D2502), and carbon-type composition (ASTM D2140 and D3238) – can be obtained from the same fi lling.


For regulated environments, SVM complies with 21 CFR Part 11, GMP, and GAMP 5.


It provides full traceability, audit trails, electronic signatures, and controlled user management. Ready-to-use pharma qualifi cation documents reduce qualifi cation effort by up to 60 %, enabling effi cient deployment in pharmaceutical QC and R&D.


SVM also supports food applications in which viscosity impacts processing and product characteristics. Edible oils and food- grade lubricants fall within the instrument’s measurement range, enabling standard- compliant analysis using low sample volumes and short cycle times.


With a temperature range of -60°C to +135°C and a viscosity range from 0.2 mm²/s to 30 000 mm²/s, SVM is perfectly suited for industrial, academic, governmental, and clinical laboratories requiring a single instrument for robust viscosity and density analysis with complete data integrity.


“Pharmaceutical and food laboratories face increasing pressure to generate reliable viscosity data while meeting strict regulatory requirements,” said Wolfgang Jud, Product Manager for the SVM series at Anton Paar. “With SVM, users can replace traditional capillary methods with a single, fully

compliant instrument that delivers viscosity, density, and derived parameters in one measurement, while ensuring data integrity, traceability, and audit readiness across both pharma and food applications.”

Proteins are essential macromolecules made up of carbon, hydrogen, oxygen, nitrogen and sulphur, and they play a central role in nutrition, metabolism and food quality. Because nitrogen is the defi ning element of proteins, protein analysis in food and beverage testing is typically based on measuring total nitrogen content.


Accurate protein determination is vital for nutritional labelling, regulatory compliance, product development and quality control. This task can be challenging, as many food matrices contain both protein-bound nitrogen and non-protein nitrogen, making the use of standardised, validated methods essential for reliable results.


Most food laboratories rely on two internationally recognised approaches: the Kjeldahl method and the Dumas combustion method. Each offers distinct advantages depending on sample type, throughput and regulatory needs.


First introduced in 1883, the Kjeldahl method remains a global reference technique for protein analysis. It measures Total Kjeldahl Nitrogen, including organic and ammonium nitrogen, and is widely accepted by organisations such as AOAC, ISO and regulatory authorities worldwide. Known for its accuracy, reproducibility and versatility, Kjeldahl is particularly well suited to complex or heterogeneous food samples where method recognition and robustness are critical. Although it involves longer analysis times and chemical reagents, its reliability makes it a cornerstone of food analysis.


The Dumas method, based on high-temperature combustion, provides a fast and fully automated alternative. It delivers nitrogen results within minutes, requires minimal manual handling and operates without hazardous chemicals, improving laboratory safety and sustainability. While the initial investment may be higher, automation and low consumable use reduce costs per analysis, making it ideal for high-throughput and routine testing of homogeneous samples.


Velp supports food laboratories with complete solutions for both approaches, offering Kjeldahl digestion and distillation systems with varying levels of automation, as well as the fully automated NDA 702 Dumas elemental analyser for rapid, chemical-free nitrogen determination.

Monitoring disinfection byproducts in drinking water: A sensitive IC-MS/MS approach


While chlorination is essential for controlling pathogens in drinking water, it can produce harmful byproducts, including haloacetic acids (HAAs), dalapon, and bromate, some of which are potentially carcinogenic. Regulatory bodies like the US EPA and the EU have set a maximum contamination limit of 60 µg/L for the sum of fi ve key HAAs (HAA5: MCAA, MBAA, DCAA, DBAA, TCAA).


EPA Method 557 outlines a procedure for quantifying these compounds at trace levels across diverse water types. In this method, a Metrohm ion chromatograph (IC) is paired with an Agilent triple quadrupole


mass spectrometer (MS), enabling direct, high-sensitivity analysis without the need for sample extraction. The Metrohm Suppressor Module minimises eluent interference, while the Metrosep A Supp 19 column ensures excellent separation of analytes from matrix components.


Even in complex water samples, matrix spike recoveries at 1 µg/L ranged from 65–115%, and minimum reporting levels (MRLs) fell between 0.025 and 0.25 µg/L.This robust IC-MS/MS method fully complies with EPA Method 557 and provides a reliable tool for safeguarding drinking water quality.
