Supplier: LGC Standards PROMOCHEM

This solution is intended for use as a calibration standard or quality control check for chemical oxygen demand (COD).

Supplier: REAGECON

Gasoline calibration standard (two compound mix) in petroleum ether is a ready to use standard used in fuel analysis as either a calibrant or analytical control solution. This standard is used in testing for a range of aromatic and oxygenate compounds in gasoline in accordance with the ASTM D5845, using infrared (IR) instrumentation. The product can also be used to validate appropriate test methods or qualify an instrument in a regulated industry. The product is QC tested on a high performance GC-MS.

Supplier: WTW

Chromate(VI) standard solution, 1000 mg/L

Supplier: Mettler - Toledo

A slight change in temperature usually has a big impact on the conductivity value of a standard solution. A table on every bottle label indicates the conductivity values at the most common measurement temperatures.
During calibration the meter automatically references to this table for temperature compensation. If possible, calibration and measurements should be performed at the same temperature
