상품설명
Hazcat’s Cyanide Test finds cyanide in substances with pH 3-14. Some cyanide salts are insoluble in H2O or have a neutral pH. These cyanides react with acids & are hazardous: Copper-CN pH 7, mercuric-CN pH 8, silver-CN pH 8, zinc-CN pH 7. Hazcat's Cyanide Test finds cyanide in samples that test +ve Oxidizer. Other tests state: “Samples that test +ve oxidizer cannot contain CN” Not true. Oxidizers such as sodium hypochlorite & hydrogen peroxide convert cyanide to cyanate removing the “CN hazard”. Many oxidizers do not have that effect on cyanides. Compounds such as copper-CN & chromium-CN give a +ve Oxidizer Test due to Cu or Cr. CN salts can be mixed with certain oxidizers without being oxidized to cyanates. Such samples are +ve oxidizer & still contain CN Oxidizers that can be mixed with CN without reaction; whose mixtures are +ve Oxidizer include: Sodium Percarbonate, Potassium Chromate & Copper Sulfate. Hazcat's Cyanide Test has no interferences, no false +ves, no false -ves. Other tests have: False +ves: Thiocyanates – sodium thiocyanate, potassium thiocyanate, mercury thiocyanate; False -ves: cyanides mixed with: bromide, iodide, chromate, permanganate, or strong reducing agent: tin chloride, sodium sulfite, sodium borohydride or zinc metal give false -ve's. Also, Copper cyanide, palladium cyanide, mercuric cyanide & silver cyanide give false -ves. Hazcat's cyanide Test works in any matrix. If cyanide is mixed with paint, the test still works - it looks for HCN gas in the atmosphere above the sample. Other tests rely on color changes to strips of test paper immersed in the sample. If the matrix has a color, this can interfere with reading those test strips. Hazcat'''''''''''s Cyanide Test requires 1ml of liquid sample or ½ spoonful of solid sample. Other tests require 5ml of liquid sample & do not give instruction for solids · Hazcat’s reagents do not have a shelf life Other tests use papers/reagents with expiration dates
