Fluorescent indicator (silica gel)
The fluorescent indicator (silica gel staining) (FIA REAGENT) is GB/T 11132 in liquid petroleum products by hydrocarbons (fluorescent indicator adsorption) specifically for ASTM D1319 special indicator of high purity chromatographic analysis hydrocarbon content. All products are imported. All the relevant properties of the product are in accordance with the specifications of the product.
Fluorescent indicator (dyed silica gel) with brown glass bottle packaging, there are two kinds of 20g and 40g
Other products: DC precision inner diameter adsorption column and GRACE 923 grade silica gel for sale, spot supply, price concessions!
Note: the fluorescent indicator should be placed in the dark at atmospheric pressure in nitrogen preservation, which can prolong the service life, the daily use of the best removal part into the vial, and often used to avoid affecting most of the life.
The filling method of sample: the fixed clamp is positioned on the feeding section of the ball joint position, refers to the adsorption column free suspension, start vibrator, vibration side pillars, while using a glass funnel to the adsorption column filled with silica gel gradually, when mounted to the separation section of half closed, vibrator, and a layer of fluorescent indicator 3mm-5mm staining and silica gel. Start the vibrator to fill the silica gel, silica gel layer to fill tight into the feeding section at 75mm so far. When the column is absorbed, the whole adsorption column is wiped with a wet cloth. After the end of the packing, the adsorption column 4min is absorbed, and a plurality of adsorption can be filled with a bracket which is provided with a vibrator
