Y-Sodium hydroxide test reagent

Product Instructions

Test principle

Sodium hydroxide is an important chemical raw material, highly alkaline, corrosive, commonly known as caustic soda, caustic soda, caustic soda, is a highly water-soluble white solid. Widely used in soap, oil, paper, textile, printing and dyeing industry. Caustic soda is a highly corrosive industrial base, which is different from our lives edible alkali (sodium carbonate, sodium bicarbonate). Under normal circumstances, the consumption of alkali bubble things, a head is not particularly large. Bubble of the water with caustic soda made food, with a bulky foam, full of good-looking appearance, the product moisture content greatly increased, thereby increasing revenue. As the caustic soda has a strong Corrosive, caustic soda soak regular consumption of products of the digestive system will have a lot of corrosion. The speed test case for this demand, according to the consumption of sodium hydroxide and alkali (sodium carbonate, sodium bicarbonate) is developed from differences in physical and chemical properties, water-fat foods can quickly detect whether the use of caustic alkali cook. The basic principle is: the reagent is within 1 second rapid reaction with water soaking hair products, the use of the industrial base, the strip will show the green, the deeper the color, the greater the amount of that industrial base. Compared with the color card, you can estimate the caustic soaking general content in products.

Detecting steps and results of judgment

1. Take a few samples with plastic cup water soaking liquid, send a industrial base immune chromatographic assay to dipped into the among them, after 0.5 seconds, take it out of a second compare with color card. If detection test paper shown color and color card more than mark, value is 1.3 g/L color of color, can think deeper mark the soaked fluid used industrial base; If immune chromatographic assay shown color and color comparison, immune chromatographic assay shown color card equivalent to sign value rose to 0.4 g / 1.3 g/L, should be the test.

2. If the color of the test card compare with the color card, the depth of color is equivalent to the value of the color card marked 0.4 g / L to 1.3G / liter, the following tests should be carried out: to clarify with 0.5ml pipette soaking 3 drops into the hole porous colorimetric tube, add 10 drip (about 0.5ml), and instillation of 1 drop of test solution A, observation holes The changes, to see whether the hole in the liquid becomes turbid, and if there is observed a white turbidity (precipitation) generated, you can expect to use the industrial base of this soaking, the content may refer to color card marked value.

Announcements

1. Peroxide value test, comparing with the standard colorimetric card, the time should not exceed 3 minutes, the longer the sample color will be deeper.

2. For the exceeded the standard of peroxide value, the samples should be sent to the laboratory for further quantification.
