NIR Technology Australia has released the series 3000 Food Analyser. It uses near infrared (NIR) transmission spectroscopy, to measure protein, fat, moisture, alcohol, sugars and other components in a broad range of foods.

It uses a petri dish sampling system and is best suited to slurries, pastes and suspensions such as processed meats, cream cheese, dairy products, mayonnaise, peanut butter, yoghurt, sausage mix, butter and margarine.

NIR light passes through a 10mm to 20mm thick sample where the O-H, C-H and N-H bonds absorb energy in proportion to the concentration of the water, alcohol, sugar, fat and protein. The measurement takes less than one minute. For monitoring polymerisation reactions, the ability to obtain a measurement of hydroxyl number or carboxyl number can provide a manufacturer with a means of detecting end points in realtime.

Polymerization reactions can be monitored in real time using the NIR Technology Australia Software program. By initiating a reaction within a glass cuvette the software will collect spectra as the reaction proceeds and display it on the PC screen.

The same instrument can be used to measure residual solvents in polymer streams as well as water and unreacted monomers. Up to 100 calibrations can be stored in memory and when connected to a PC, the results files can be easily uploaded.

The NIT-38 polymer analyser uses a diode array spectrometer. This optical system has no moving optical components and is independent of orientation and vibration. The analyser has been designed for ease of operation and requires only two keystrokes for an analysis. Along with the compact size and rugged construction, the analyser can be used in the laboratory or in the processing plant.

The built-in computer controls the operation of the instrument, computes the parameters for the samples and displays the results on the LCD screen. Data can be stored in the analyser's memory and later downloaded onto a PC. Alternatively the analyser can be controlled from a PC and the data stored in the PC.

NTAS provides a suite of routines to allow PLS calibration development, spectral collection, display and manipulation, library search and discriminant analysis.
