Understanding of Catalog Number Assignments

The contained product assignations are based on using almost self-descriptive alpha-numeric combinations of the element of primary interest, the matrix and the number of individual standards comprising a complete set. The purpose of this explanation is to assist the reader in interpreting the product catalog number thereby reducing or eliminating the potential possibility of introducing errors in the ordering process and most importantly to receive the items requested without undue delay.

The products of similarity have also been assembled in table format with each appearing in their respective sections for ease of location and reference further simplifying the selection process.

The product prefix is generally in alpha format that infers the classification of the product matrix. The characters following the alpha format may also be in alpha format that serves to define the product in greater detail. The sets of alpha characters are generally followed by a numeric suffix that relates to the number of individual standards comprising a complete set.

The following will be helpful in deciphering and understanding the nomenclature.

Alpha-Strings:
The Alpha-strings denote the type of matrix.

Elements of Primary Interest:
In most instances, the element of primary interest, but not necessarily of analytical interest, is placed prior to the alpha-string as a prefix. For example, in the aforementioned alpha-strings the appearance of an “S” prior to the alpha-string “MO” is indicative that the element of primary interest is Sulfur, “SMO”; similarly “SDF” would represent Sulfur in Diesel Fuel; “SRO” would represent Sulfur in residual oil; “SEPA” represents Sulfur according to the EPA methodology; “CLSMO” would represent Chlorine and Sulfur in Mineral Oil; “CLWO” would denote Chlorine in “Waste Oil”; “SNVMO” and SFNVMO” Sulfur with Nickel and Vanadium and Sulfur with Iron (Ferrous) with Nickel and Vanadium, respectively, in Mineral Oil. “SNVRO” and SFNVRO” implies Sulfur with nickel and vanadium and sulfur with iron (ferrous), nickel and vanadium in residual oil, respectively.

Numeric Sequence:
The numeric sequences following the alpha-strings are generally related to a combination of specifications. The first numeric sequence relates to the number of standards comprising a set, a procedure or “L” or “H” representing low or high in concentration, respectively, in SEPA(G)L, where “S” is Sulfur, “EPA” connotes the methodology “G” represents “Gravimetric” and “L” represents “Low” concentration. For multi-element concentrations the combination of the numbering sequence denotes the number of multi-elements in a standard and their respective concentration levels, e.g. “WM20-10”, Wear Metal containing 20 elements each at a concentration of 10 PPM. “A” is representative of sulfonated wear metal constituents. Concentrated Lubricating Oil Metal Standards, LOMS” is simply followed by the chemical symbol and its concentration level.

Table Groupings:
Similar Alpha strings are arranged in tabular form and whenever possible within proximity to each other and on the same page.
