CSI Gas Standard Mixture Tolerances
PRIMARY STANDARD – The most accurate and reliable class available. Prepared gravimetrically on high capacity, high precision scale. All components certified to +/- 1 % analytical accuracy by gas chromatography or other suitable analytical method.
Certified standard – Manufactured by a combination of pressure and/or weight measurements. Prepared gravimetrically on high capacity, high precision scale. Unless stated otherwise, all components are certified to +/- 2 % analytical accuracy by gas chromatography or other suitable analytical method. Widely used and considered the most cost-effective solution for various applications.
gravimetric standard – Manufactured by a combination of pressure and/or weight measurements. accurate and reliable class available. Prepared gravimetrically on high capacity, high precision scale. No analysis performed, reported values are based on calculated and actual gravimetric results.
