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.
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.
The iCE 3500 atomic absorption spectrometer allows simple analysis of cadmium in chocolate, while SOLAAR software enables easy method development.
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.
The range of Waco can quality testing equipment includes video seam monitors, can seam thickness gauges, score groove for pop-up openers, countersink depth, flange width, can strippers, enamel raters and the Accuseam 2000 computerised double seam control system for food or beverage cans.
The FiveGo dissolved oxygen can be used to simplify measuring of dissolved oxygen and is suitable for numerous food and beverage applications as well as for use in other industry segments.
The IDM Instruments F0022 Flexseal advanced leak detection system, designed in conjunction with Amcor Research and Technology, can be used for monitoring the seal performance of flexible and semi-rigid packages.
The Cropscan 2000B near infrared transmission analyser is suitable for use by grain processors, flour millers, stock feed manufacturers, oil seed crushers, meal manufacturers and biofuel producers.
The Anton Paar L-Dens 323 density meter for the food industry is available with wetted parts made of Hastelloy. The meter is suitable for the continuous monitoring of the density or concentration of liquids when an accuracy of 1x10-3 g/cm3 is required for the density results.
Portable ATP bioluminescent-based tests are very common in many food processing plants, and the test is now a widely recognised method for rapid hygiene testing. However, not all ATP systems are the same, and some may provide false and variable results. Potential sources of variability include the luminometer, temperature, sanitiser residues, storage condition of the swabs and operator technique.
