TRUE NORTH
Gas-in-oil standards
FEATURES & BENEFITS
Features
- 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
