At present, there are mainly thin-layer chromatography, high-performance liquid chromatography, gas chromatography, and liquid-mass spectrometry. Thin-layer chromatography is mainly used for qualitative analysis. It has poor agility in the quantitative aspect of alcohol monomers. Defects such as color instability make the plant sterols unable to meet the requirements of accurate quantitative analysis. Although the gas chromatography technique has a high resolution and good thermal stability, the disadvantage is that the reagents are highly toxic and the detection cost is high. Higher operating temperatures will destroy the molecular structure of the sample during the measurement process. At present, liquid-phase mass spectrometry technology, as a more sensitive and selective detection method, is providing a new possibility for the detection of plant alcohols, and our Wuhan healthdream’s detection method is precisely this, with high accuracy. Although the purchase and maintenance costs of machinery and equipment are high and require high operators, it has high accuracy and sensitivity and strong stability.
Our Wuhan healthdream is supplying xylosterol, soybean sterol, etc., food grade, with a content of about 75%. Welcome to inquire or send an email to our mailbox through the official website www.healthdreambio.com.
