The determination of the protein content of a sample is a very important task in many fields, so the choice of a reasonable sample protein content method becomes critical. However, although there are many methods for determining the protein content of a sample, there are Kjeldahl method, biuret method, Folin phenol method (Lowry), ultraviolet method, pigment binding method (Bradford method), BCA method, colloidal gold measurement method, etc., but Kjeldahl nitrogen analyzers developed based on Kjeldahl method are favored in the industry. Why?
Kjeldahl method is a classical method for determining the protein content of samples. It is widely used in many fields. The Kjeldahl nitrogen analyzer developed based on Kjeldahl method not only inherits its advantages, but also optimizes its technology. Whether it is measurement accuracy or ease of operation, there is a significant improvement. Taking the automatic Kjeldahl analyzer as an example, the instrument has high sensitivity, fast analysis speed, wide application range, less sample required, simple equipment and operation, etc. It is the first choice for the determination of protein content in many industries. Instruments, in the minds of industry personnel occupy an important position.
In fact, with the rise of domestically produced instruments and advances in technology, the domestic Kjeldahl nitrogen analyzers have gradually replaced the imported Kjeldahl nitrogen analyzers with advantages such as excellent price and good quality, which have been widely used in the industry. With its popularization and application, more and more industry personnel have also felt the convenience brought by the instrument. In addition, Kjeldahl nitrogen analyzer has many models and functions, mainly semi-automatic Kjeldahl analyzer, fully automatic Kay Nitrogen analyzers, etc., these different types of nitrogen analyzer products meet the requirements of different industries and different standard protein determinations. Therefore, in many testing laboratories, Kjeldahl nitrogen analyzers are favored by the industry and become a must. One of the instruments.
