Updates - Proficiency Testing


2018 Fees

Thanks to efforts to maximize efficiencies by our collaborator laboratories, CALA is happy to announce that we will be able to maintain most proficiency testing fees at the 2017 prices.  Only a few will increase as a result of increased cost of production.  The proficiency testing price list will be published in November 2017.



New Test Groups

CALA will be adding three new test groups to the Proficiency Testing program, all in a soil matrix.

C43 Solids in Soil

This test group will include percent moisture, total solids, volatile solids and fixed solids.

C44 Nutrients in Soil

This test group will contain ammonia, total phosphorus, total kjeldahl nitrogen and organic carbon.

C45 Anions in Soil

This test group will contain bromide, chloride, fluoride, nitrate, phosphate and sulphate.

These test groups will be offered in January and June. For the January 2018 round, CALA will be offering these test groups at no cost to participants (international participants will still be responsible for shipping costs). A limited number of samples will be prepared and they will be made available on a first-come first-served basis. If your laboratory would like to participate in these PT, please submit the relevant portions of the CALA http://www.everwebapp.comPT application.
