Sensory testing method and instrumental analysis method which is important to try to analyze the reasons for it

Instrumental sense is more accurate.

Instrumental analysis is more accurate than sensory evaluation, high precision, only in the sensory feel good things to do instrumental analysis.

Instrumental analysis is an analytical method using a more specific instrument, which is based on the physical or physicochemical properties of a substance. According to some kind of physical properties of substances, such as relative density, phase transition temperature, refractive index, spin and spectral characteristics, etc., without chemical reaction, direct qualitative, quantitative, structural and morphological analysis of the method, known as physical analysis, such as spectral analysis method. According to some physical properties of substances in chemical changes, qualitative or quantitative analysis of the method is called physicochemical analysis, such as potentiometric analysis. Instrumental analysis method has the characteristics of sensitive, fast, accurate, fast development and wide application. Mainly includes electrochemical analysis, optical analysis, mass spectrometry, chromatography, radiochemical analysis. Forensic toxicology analysis of commonly used instrumental analytical methods are spectral analysis, chromatography and color / mass spectrometry, the latter two have a very good separation and qualitative and quantitative analysis of performance.
