The potential for food contamination, economic adulteration, and other related food safety issues are leading to an increased awareness of the important role that food testing laboratories play in ensuring the safety and quality of our food supply. The requirements for sophisticated instruments and well-trained, experienced analysts in food safety laboratories are essential factors in making certain that food is safe from chemical contamination.
The GreenLight range of food safety tests provide easy, same-day detection and enumeration of bacteria in food samples by measuring bacterial oxygen consumption (bacterial respiration) and equating oxygen consumption to microbial load.
The Pulsar Guard 2010 sensor detects structure-borne acoustic signals caused by the movement of material. This movement causes impacts and frictional contact with a containing face, eg, the inside of a pipe. The sensor is fastened to the outside of the structure and its high frequency detection picks up these signals, which are often undetectable to the human ear. The high-frequency detection allows use in environments where there is a high degree of machinery noise or process noise, without interference. The sensor’s non-invasive nature allows easy fit to most pipes, chutes or feed mechanisms without stopping the process.
The CarboPac SA10 column has been specifically designed for the fast, high-resolution analysis of food and beverage carbohydrates. The column is composed of a macroporous substrate coated with a strong anion-exchange layer of latex nano beads which provide high capacity and rapid high-resolution separations.
The Mecmesin Advanced Force Gauge (AFG) is a versatile and fully featured digital force gauge that has been specifically designed to measure force in tension and compression (push or pull) with optimum precision and performance.
BevScan is a device that can be used to analyse and classify wines without opening the bottle or disturbing the contents in any way.
The Koehler Automated Colorimeter is a microprocessor-controlled spectrophotometer with a wavelength range from 380 to 720 nm for colour measurement or 320 nm up to 1100 nm for routine analysis. It can carry out an exact colorimetric evaluation in conformity with several ISO/ASTM standards with just a single measurement and display the result in terms of traditional colour systems such as Iodine, Hazen/APHA or Gardner colour numbers as well as in modern CIE-L*a*b* colour values.
The Hach H series rugged portable meter systems provide a large LCD with LED backlight and measurement of pH (ISFET or glass), mV, temperature, conductivity, total dissolved solids (TDS), salinity and oxidation reduction potential (ORP).
European agri-food company Conserve Italia is using Thermo Scientific GC/MS and LC/MS systems for fast and reliable pesticide analysis of food products. Conserve Italia processes around 650,000 tons of raw materials each year, including fruits, vegetables and tomatoes, and provides the European market with finished goods such as fruit juices, canned vegetables and tomato sauces and purees. The organisation is using the Thermo Scientific TSQ Quantum GC and TSQ Quantum Access Max triple-stage quadrupole mass spectrometers to achieve compliance with maximum residue limits (MRLs) specified for pesticides in food. By using the instruments, the laboratory has significantly increased sample throughput as well as experienced substantial time and cost savings.
The CRIUS Solisense turbidity meter ranges from 0.02 NTU (FTU) to 8% solids and is claimed to be unique in its ability to measure from NTU to percent solids in one sensor. It is suitable for potable water monitoring, filter monitoring, mixed liquor suspended solids monitoring, sludge monitoring centrate monitoring, filtrate monitoring and other applications where a traditional turbidity meter or suspended solids analyser would be used.
Mecmesin Emperor software for tension and compression testing has been designed for use in quality control laboratories where the mechanical properties of manufactured products need to be assessed on a routine basis.
Corona Giken has released the STtuve III, a simple and reliable method for the in-house testing of surfaces for the presence of bacterial contamination. Designed as a fully self-contained system, each test contains a sterile sampling swab, selective bacterial culture media and a sanitising solution.
The iCE 3500 atomic absorption spectrometer allows simple analysis of cadmium in chocolate, while SOLAAR software enables easy method development.
Dionex Application Note 231: Determination of Melamine in Milk by Ion Chromatography with UV Detection describes a method that uses the IonPac CS17 column and UV detection to determine the amount of melamine in samples of milk, powdered milk and a milk-containing candy.
Trakya Birlik, an agricultural cooperative based in Edirne, Turkey, has purchased 21 Oxford Instruments Magnetic Resonance MQC-5 benchtop NMR analysers. The instruments will be used as part of an initiative to improve sunflower seed oil yield.
