Full range of True North standards in mineral oil, synthetic esters oil, silicone oil and natural esters oil
NIST-traceable ensuring proper calibration of gas extraction and chromatography
Shelf life 30-day (regular) and 60-day (long-life)
The 9 gases typically analyzed in DGA: H2, CO, CH4, C2H2, C2H4, C2H6, CO2, O2 and N2
Benefits
The only way to verify performance of the entire analytical process
Provide a common base for calibration of all DGA systems, independently of gas extraction method, gas detection technique and equipment used
Common reference guarantees significance of data trending using results from different laboratories
Excellent for client or laboratory assessment of analytical performance using blind samples
TRACEABILITY
Each bulk standard of True North oil is produced using NIST traceable gas concentrations and NIST traceable calibrated balances
Bulk lots are continuously monitored for stability and nominal concentrations are validated statistically to reach a 95% degree of confidence on the precision range stated for each gas concentration
True North DGA Oil Standards are extracted from bulk standards on the day they are shipped
A Certificate of Concentration is delivered with each sample for traceability
