Cyanide (Colorimetric)

Detection of cyanide by colorimetric analysis; also provides semi-quantitative cyanide levels in forages.

Learn more about testing for cyanide and nitrate in forages in the online Education Library.

NameCyanide (Colorimetric)
Code1017
SectionAnalytical Chemistry
SpeciesBovine, Caprine, Cervid, Exotic, Non Animal, Ovine
SpecimenOne or more of the following: 8-15 stalks of fresh forage, baled hay core sample (single probe), frozen rumen contents, frozen tied off stomach (small animal).
Sampling Requirements

Freeze rumen content or tied off stomach (small animal) immediately upon collection and ship to arrive frozen. 

For standing forage, collect 8-15 plants per fenced area. To lighten for shipping, collect all the leaves from the grass plants of one fenced area into a single paper or plastic bag as one sample. 

For baled hay, obtain a drill and hay probe; one may be available to borrow from your local Texas A&M AgriLife Extension Service office. Obtain a glass jar with deep threads (canning or mayonnaise, not pickle). Drill the probe into the bale and withdraw, immediately transferring the core sample into the jar and sealing it tightly. Do not put more than one probe sample in the jar. To test more than one bale, obtain additional jars. With written instruction from a client, up to 4 jars may be tested simultaneously as one sample. If more than one sample is shipped, mark each with identity of the fenced area of hay bale lot. 

Collection Container

Forage and rumen content: sealed, leak-proof plastic container or bag. 

Hay: collected and shipped in a tightly sealed glass jar.

Packing Instructions

Samples should arrive at the lab within 24 hours of collection. Rumen content must arrive frozen.

Special Instructions

This is a time sensitive test due to the volatility of cyanide. Contact the lab if uncertain of shipping and sampling instructions.
