NIRS, AES, and ANA - Tissue Testing Methods
January 1, 1995
Holy mackerel, how did we get ourselves in this deep? It’s easier than you might imagine. Many of you recently participated in a tissue analysis survey that compared these techniques. The most popular method of tissue analysis requires a laborious chemical extraction and expensive analytical tools, such as atomic emission spectroscopy (AES) for the major and minor elements except nitrogen and an automatic nitrogen analyzer (ANA) for nitrogen. More recently, near infrared reflectance spectroscopy (NIRS) has captured the interests of…
