Introduction to moisture analyzer

An instrument capable of detecting the moisture content of various organic and inorganic solids, liquids, gases, and the like is called a moisture analyzer. According to the principle of measurement, it can classify physical and chemical assays. Physical weight measurement methods commonly used are weight loss methods, distillation layering methods, gas chromatography methods, and the like. The chemical measurement methods mainly include Karl Fischer, toluene, and the like. The International Organization for Standardization has identified the Karl Fischer method as an international standard for the determination of trace moisture. Our country also uses this method as a national standard to measure trace moisture. Common weight loss method moisture meter has halogen moisture measurement, infrared moisture analyzer, microwave moisture analyzer and so on. Common Karl Fischer moisture analyzers mainly include a volumetric Karl Fischer moisture analyzer and a Coulometric (electricity method) Karl Fischer moisture analyzer.

The significance of moisture analyzer detection

1. It is one of the important quality indicators

A certain moisture content can maintain food quality and extend food preservation. The water of various foods has their own standards. Sometimes, if the moisture content exceeds or decreases by 1%, it plays a big role in both quality and economic benefits.

2. It is an important economic indicator

The food factory can calculate the material based on the moisture content of the raw materials. For example, the fresh milk has a water content of 87.5%. How much does it take to produce one ton of milk powder (7..1 milk powder rate) for this milk production milk powder (2.5% water content)? Material balances like this can be done on the basis of moisture determination. This also guides the management of production.

Another example is the production of bread. How many kilograms of water do you need for 100 kg? Material balance must be done first. The toughness of the dough is related to moisture. Add more water and the dough is soft. Add less water and the dough is hard. The bread made is not large and affects economic benefits.

3. The content of water is closely related to the growth and biochemical reaction of microorganisms.

Under normal circumstances, it is necessary to control the water to a little lower to prevent microbial growth. However, it is not as low as possible. Microbial action is usually more intense than biochemical action.From the above three points, the importance of measuring moisture can be explained. Moisture is a must in our food analysis.

Spectrophotometer, also known as spectrometer, is a commonly used analytical instrument for qualitative and quantitative analysis of the substance by measuring the absorbance of light at a specific wavelength or a certain wavelength range.

Spectrophotometer comes in many varieties and uses. Visible spectrophotometers are mainly used in chemical analysis such as metallurgy, medicine, food industry, medicine, health, chemical, school, biochemistry, petrochemical, quality control, environmental protection and scientific research laboratories. It is a single-beam spectrophotometer that measures the absorbance of visible light (400-760 nm) of a substance to be tested and qualitatively and quantitatively analyzes it.

The atom first absorbs the spectrophotometer source and then emits the measured characteristic spectrum radiation. It is absorbed by the ground state atoms of the element to be tested in the sample vapor after passing through the atomizer. The content of the element to be measured is determined by measuring the magnitude of absorption of the characteristic radiation. It is one of the conventional instruments for the analysis laboratory of production, education and scientific research units.

The UV-Vis spectrophotometer is used to measure the absorbance of the sample to visible or ultraviolet light (200-760 nm) and to qualitatively and quantitatively analyze it. It has been widely used in the fields of drug analysis, drug testing, sanitary and epidemic prevention foods, environmental testing, chemical engineering, scientific research, etc. It is an indispensable instrument for production, scientific research and teaching.

Ultraviolet light meter detects the intensity of ultraviolet radiation, and is used to measure the intensity of ultraviolet radiation in the fields of photochemistry, flaw detection, ultraviolet light source, plant cultivation, large-scale integrated circuit lithography, and polymer material aging.

Ultraviolet light is ultraviolet radiation, which is electromagnetic radiation with a wavelength of 100-400nm. It refers to the intensity of ultraviolet radiation per unit area. The instrument commonly used to detect the intensity of ultraviolet radiation is called an ultraviolet radiometer, also called an ultraviolet illuminance meter. Although it is called an illuminance meter, it has nothing to do with illuminance. Illumination studies the visible light that the human eye can see. The ultraviolet light meter measures ultraviolet light, which is invisible to the human eye, so it is related to the irradiance.

Irradiance is called radiant flux density and it is the integral of radiance to the solid angle. The area of the irradiance is integrated to obtain the power of the radiation.

Definition 1: Radiated energy projected onto a unit area per unit time.

Definition 2: The radiant energy received by an object on a unit time and unit surface. The unit is W / m2.

Definition 3: The radiant flux on an infinitely small bin containing the point divides the area of the bin.

Definition 4: Radiated energy projected onto a unit area per unit time. Irradiance (Ee, E) is a physical parameter, which is the amount of radiant energy received per unit area on a given surface. Unit: Watt / square meter.

The wavelengths measured by the UV radiometer are divided into UVA (320nm-380nm), UVB (280nm-320nm), and UVC(200nm-280nm). ShenZhen Xinzhibang UV Radiometer LS125 can detect UVC, UVB, UVA various wavelengths. It is widely used in sterilization, curing, pharmaceutical factory testing, sewage treatment, disease control center, non-destructive testing, welding arc testing, ultraviolet aging experiment testing and other industries.

Overview

Hygronom is used to measure the humidity of flue gas emitted by pollution sources. According to measured humidity, the precision humidity meter converts wet gas concentration into dry gas concentration. In addition, it also can be used in industrial online humidity monitoring.

HM-200 hygronom is an intelligent humidity/ oxygen transmitter, which employs microprocessor as the core, and frequency conversion icon oxygen sensor as a measuring unit. The installation method adopts a heat tracing pipeline installation. It is a self-developed product, of which, the core component is from Switzerland.

Under the effect of the air pump, the flue gas inside the stack enters the measurement module after heating from the heat tracing probe. The whole process of extraction, measurement, and discharge is with heat tracing to prevent gas from condensation, which will affect the measurement of moisture in the flue gas. The flue gas enters the measurement module after heating and the frequency conversion icon oxygen sensor will start to measure gas concentration. After the measurement, the gas can get into an analyzer for the measurement of other components.
