Alfa Aesar offers a line of calibration standards specifically designed for the analysis of sulfur in light mineral oil (20cSt mineral oil). These standards are ideally suited for ASTM Methods D2622, D4294, D7039, D7217, D7220 and others.
All Specpure® Sulfur in Light Mineral Oil standards are manufactured from the highest quality raw materials available. These standards are made up on a weight/weight basis using balances which are routinely calibrated using NIST-traceable weights. All Alfa Aesar standards are accompanied by a Certificate of Analysis which states the actual concentration and the traceability to NIST. They are guaranteed to be stable for one year from the ship date, provided they are kept tightly capped and stored under normal laboratory conditions.
