WebNear 215 nm, the changes in absorbance toward the short-wavelength end are greater than the changes in absorbance toward the long-wavelength end (Fig. 5). As a single-wavelength UV-VIS detector normally offers a wavelength bandwidth of approximately 8 nm, care is required when performing gradient elution at 50 % or more Liquid B. WebOverview. Hydrogen cyanide (HCN) is a colorless or pale-blue liquid or gas with a bitter, almond-like odor. Hydrogen cyanide interferes with the body’s use of oxygen and may cause harm to the brain, heart, blood vessels, and lungs. Exposure can be fatal. Workers may be harmed from exposure to hydrogen cyanide.
