20 Innovative Accessory for ATR Spectroscopy
The Specac Quest™ ATR accessory is a versatile single-refl ection ATR accessory designed for laboratory spectroscopic sample analysis in the mid- and far-infrared. With innovative optical design and durable monolithic diamond ATR crystal option, it sets the benchmark in performance and value for ATR spectroscopy. Recently, the capabilities of the Quest have been expanded to include a heated puck and the innovative Arrow™ system of silicon consumable slides.
The Heated Puck is capable of analysing both liquid and solid samples at up to 110°C. The temperature of the accessory is controlled from the Specac Temperature Controller Software app which plots the current accessory temperature against experiment time, along with the target temperature the program is trying to reach.
The Arrow™ is a system for batch preparation and analysis of liquid samples, using a thin silicon wafer as the ATR element. Each Arrow is a slide containing a single silicon internal refl ection element that can be treated as a low-cost consumable for experiments requiring high volumes of samples or complex pre- treatments. By employing a single Arrow per sample, cross-contamination is avoided - especially useful in forensic and microbiology applications.

Unlocking Oil and Fat Analysis using Benchtop NMR
The fat content of foods is always a critical factor as following a healthy diet becomes increasingly important to consumers. This means manufacturers need to ensure accurate, fast and clean measurement of oils and fats in a variety of foods, including snacks and chocolate. Moreover, the presence of oils and fats is a major determinant in texture, mouthfeel, fl avour and quality - therefore it is vital to ensure consistency across the production process. Nuclear Magnetic Resonance (NMR) can help in this objective with a rapid, simple and precise method for the measurement of fats and oils. Careful control of oil content in snack food is essential in ensuring product consistency in the global snack food industry, one of the fastest growing segments in foods today. It is a highly competitive industry where success requires high quality and, above all, a consistent product to ensure repeat consumption. Likewise, in the chocolate sector, its enduring consumer appeal rests on its sensory properties and consistency. An article from Oxford Instruments discusses the quantifi cation of fat content during and after processing for end-product consistency.

Portable Quadrupole Analyser for Environmental Field Studies
The Hiden pQA portable gas analyser is a versatile mass spectrometer and offered with a range of interchangeable sampling inlets to suit a broad application range. MIMS inlets are offered for analysis of dissolved species in ground water, fermentation cultures, soil samples, and general applications where analysis of dissolved species in liquid sample is required.
The system is suited to gas analysis applications, where sample volume is small, and for environmental applications where detection of low concentration levels is required. The pQA system has a mass range of 200 amu and sub ppb detection levels. Extended mass range to 300amu is optional.
The system is supplied in a Pelican® laboratory use.
case and can be powered by a 12 V supply for fi eld use, battery and/or solar powered, or a 220 V supply for
Sampling inlet systems are offered for a broad application range including: Direct membrane inlet probe for immersion and/or insertion in liquid or sludge sample, soil core sampling for example; Recirculating probe for analysis of sample with continuous fl ow, extracted sea or estuary water for example; Flow through probe, low fl ow design for denitrifi cation studies.
The system includes: Quadrupole mass spectrometer system from the RGA series with mass range options 200 amu; Mass spectrometer analyser manifold and UHV pump set with a manually valved dissolved species probe with silicone rubber membrane; Ion Gauge and interlocks to provide protection for the mass spectrometer in case of over pressure; fast acting shut off valve between the dissolved species probe and mass spectrometer manifold to protect the mass spectrometer in case of membrane failure - the valve is interlocked with the integral UHV pressure gauge; supplied in a ruggedised Pelican case for usability in the fi eld; can be powered by a 12 V supply, from a vehicle power outlet, for example as well as a standard power outlet for laboratory use; total weight is less than 40 kg.
