Instrumentation for Measurement of Fluid Dairy Samples – Something Old and Something New
October 23, 2019 | 2:00 - 3:00 p.m. ET
Instruments designed for the compositional analysis of fluid dairy products - specifically milk, cream, whey and condensed/membrane filtered derivatives of milk and whey - have centered on the use of vibrational spectroscopy. Analyzers using optical filters were the first instruments available to industry for compositional analysis of milk for fat, protein, and lactose. Later, FT-IR analyzers were developed to measure the same components, using the same signals as optical filter technology. Bulletin of the IDF N° 497 2019: Applications of Near Infrared Spectrometry for the Analysis of Milk and Milk products introduces the pending extension of ISO 21543 / IDF 201, first released in 2006, to include measurement of milk and other fluid dairy samples using Near Infrared Spectrometry.
In this presentation we will present a high-lever overview of the instrument design elements required to achieve the expected accuracy and repeatability for the dairy industry, comparing the desirable attributes of each instrument platform in terms of cost, ease of use and required maintenance.
