Customized Wholesale Silicone Rubber Sheets Silica Gel Plate Multicolor

Mica plate:

Product name Silica gel plate chemical industry on the term "silica gel plate" is just an abbreviation, its full name should be called the thin-layer chromatography silica gel plate, it is also called high tear silicone boards with high purity thin-layer chromatography silica gel (powder) to a certain amount of binder spray, its general for glass panel, this year, foreign popular use aluminum foil to make attached board face.

The board surface is required to be pure white, even and fine. The main component is SiO2•nH2O, which has stable chemical properties and does not react with other acids and bases except strong bases and hydrofluoric acids (but experience shows that it is not resistant to corrosion in 40% nitric acid fog at 60 ° C). Thin-layer chromatography silica gel plate can be directly used for qualitative or quantitative analysis of various types of organic substances, and has been widely used in the identification of trace impurities and main components of medicine, pesticide, Chinese herbal medicine, organic chemical products, food and food.

Silica gel plate is made of high quality thin layer chromatography silica gel as raw material, thin layer chromatography silica gel plate, high efficiency thin layer chromatography silica gel plate, it is made of high quality thin layer chromatography silica gel with appropriate adhesive coated on the glass substrate, and has a specified pore volume, specific surface and pore distribution.

Activity: (separation of indigo, Sudan red, dimethyl yellow) three color separation.

The characteristics of

1. The separation effect is good, and the number of trays is high.

2. Small spots for serial analysis.

3. Short separation time.

4. High sensitivity, clear spots and non-diffusion.

parameter

1. The thickness of silica gel plate coating can be divided into:

Analysis plate: 0.2 mm

Preparation plate: 0.3-- 0.4mm, 0.4-- 0.6mm, 0.6-- 1mm

2. According to the specifications, it can be divided into:

G type H type GF254 HF254 is also divided into ordinary board and efficient board!

H is short for Hard

G is short for Glutinous

F is short for Fluorescent

Silica gel H: no adhesive, no fluorescent agent;

Silica gel G: without fluorescent agent, containing plaster of Paris binder;

Silica gel HF254: contains fluorescent substances, which can be used to observe fluorescence under ultraviolet light with wavelength of 254nm;

Silica gel GF254: contains both plaster of calcined and fluorescent agent, which can be used to observe fluorescence under ultraviolet light with wavelength of 254nm

3. The method of discriminating classification

Different types of silica gel are different in gypsum content, which is reflected in the viscosity of silica gel is different, the higher the gypsum content, the more viscous. This is marked on the bottles that sell silica gel. For example, silica gel H is very loose, and silica gel G is generally relatively moderate in viscosity.

The classification and advantages and disadvantages of silica gel plate

Silica gel plate is made of high quality thin layer chromatography silica gel as raw material, thin layer chromatography silica gel plate, high efficiency thin layer chromatography silica gel plate, it is made of high quality thin layer chromatography silica gel with appropriate adhesive coated on the glass substrate, and has a specified pore volume, specific surface and pore distribution. At present, the silica gel plate on the market is mainly divided into two types according to the molding process.

First, extruded silica gel plate.

Extruded silica gel plate is formed by extrusion molding machine. The extruded silica gel sheet and ribbon can be circling together for several meters, and the length can be cut freely.

Advantages: fast maneuvering performance, low cost, high yield, fast production speed, free cutting length, uniform thickness.

Disadvantages: In the later stage, it needs stamping die cooperation to cut out a specific shape,

Two, molded silica gel plate.

The molded silica gel plate is a fixed size silica gel sheet formed by silica gel mold and high temperature vulcanization. The silica gel plate has a limited area and a fixed length and width.

Advantages: stable production, good quality of raw materials, color, hardness, good control of raw material grade, consistent size.

Disadvantages: the output of the bottom, the cost is 2-3 times of the extrusion of silica gel plate, and the thickness is uneven.

use

It can be directly used for rapid separation and qualitative or quantitative analysis of various types of organic materials. It has been widely used in the identification of trace impurities and main components of medicine, pesticide, Chinese herbal medicine, organic chemical products, food and food.
