FLEX 2 autosampler.

This application note will compare dynamic headspace and Solid Phase Micro Extraction (SPME) sampling techniques for the detection of the volatile components in plain yogurt. Yogurt has been around for years and the health benefits are well known. With the advent of Greek yogurt, there has been increased interest and consumption of yogurt. Yogurt is a very healthy food. It has the nutrients found in milk like calcium, magnesium, potassium and vitamins B-2 and B-12. Furthermore, yogurt has the benefit of containing bacteria that aids in digestion. With all of these benefits, many food companies have increased interest in selling yogurt products. Thus, analysis of yogurt becomes essential for creating a product that will sell.
