The procedure requires about 15 minutes and employs a test strip. Inorganic As+3 and As+5 are converted to arsine gas. This reacts with the test strip in a closed container and produces yellow to brown colors on the strip. The strip color is compared to a color chart to determine concentration in ppb.

Manufacturer: Laxco, Inc. Brand: Laxco Inc Model: Alpha-1000

The Laxco Alpha-1000 visible-light spectrophotometer has a manually-adjustable 400 to 1000nm wavelength range, a 15nm spectral bandwidth, and a tungsten-halogen lamp, and is used for routine testing and teaching laboratory applications. The instrument provides direct measurement of routine absorbance and transmittance measurements. The 15nm bandwidth is used for quality control measurements when high resolution is not required. The tungsten-halogen lamp and single detector support measurements in the visible range. The instrument has a single-cuvette sample holder. The digital display indicates transmittance and absorbance measurements, and USB and RS-232 ports provide data output to a computer (sold separately).

A spectrophotometer is a device used to measure and analyze aspects of light absorption in liquids and solids. Readings are displayed in digital or analog format. A spectrophotometer can have a handheld body for field use, or a bench-top body for laboratory applications. It may have one or more adapters to enable it to measure surfaces or liquids. A spectrophotometer is used for testing and measuring in anatomy, chemistry, agriculture, process plant, food and beverage making, homeland security, and educational applications.

Liquid Color Standards range from water white through yellow to deep amber. Liquid Standards 1 through 8 are solutions of potassium (No Suggestions). They are light in value, have a very slight greenish hue and are most often used in testing unheated liquids. Standards 9 through 18 are solutions of ferric chloride and cobalt chloride; they are darker and are generally used to test varnishes, oil and resins which have reached color through heating.
