Static Testing

Acid Base Accounting (ABA)

CANTEST offers all acid base accounting (ABA) procedures including standard Sobek, modified Sobek, modified ABA, Net Acid Generation (NAG), and BC Research Initial Test methods. Analyses commonly include paste pH, fizz rating, total sulphur, sulphate sulphur, sulphide sulphur and neutralisation potential (NP). CANTEST calculates and provides maximum potential acidity (MPA), carbonate NP (NNP) and net NP.

Static Water Leaching Procedures

Short-term water extraction (18 to 24h) procedures are routinely conducted to determine the presence of readily leachable contaminants. Methods include the Modified SWEP, SPLP and Meteoric Water Mobility Procedure (MWMP). Extract analysis commonly includes pH and dissolved metals by ICP-ES or ICP-MS. Other possible analytes include alkalinity, acidity, sulphate, TDS, bicarbonate, Cl, F, nitrate-N, nitrite-N, ammonia-N, TKN, total P, ortho-phosphate, CN species and other anions.
