Product Codes

Here's your secret decoder ring for ASI Standards

The majority of our Check Standards are coded as ElementMatrix-Concentration-Size (i.e. SMO-10-100; Sulfur in Mineral Oil, 10 mg/kg, 100 ml bottle).

The majority of our Custom Calibration Standards are coded similarly, as ElementMatrixNumberofStandards-Ultra Low/Low/High Concentrations-Size (i.e. SRO6-H-200; Sulfur in Residual Oil, 6 standards per set with any standard concentration above 1.00 Wt% in 200 ml bottles.)

We differentiate Calibration Standards based on the concentration of the standards in the set. Any standard with a concentration of 1 mg/kg and below is considered Ultra Low, and will coded as UL. Any standard with a concentration greater than 1 mg/kg up to 1.00 Wt% is considered Low, and will be coded as L. Any standard with a concentration greater than 1.00 Wt% is considered High, and will be coded as H.

Multi-element standards are coded based on the number of standards and elements in the set. We recommend lubricating oil as the matrix for multi-element standards to help with stability. Can you guess what Elements in Lubricating Oil Calibration Standards, 7 standards per set, 5 elements per standard in 100 ml bottles would be? ELO7-5E-100! ELO (Elements in Lubricating Oil)7(7 standards) - 5E(5 elements)-100(100 ml bottle). Note that this product code will be used for any set of 5 elements.

You can always refer to our online shop for product codes. Here's an example of one of our Sulfur in Crude Oil Check Standards

We are currently revamping our ampule and polyethylene product codes. If you will be at Gulf Coast Conference, come say hi and ask for our new product flyers.

We will also have a deep dive blog post on ASI Standards product codes in the near future.
