Calibration Standards

Edetate Disodium Dihydrogen, Dihydrate, Primary Standard is a single component organic chemical reference standard. Reference standards are particularly important for analytical chemistry since most analytical instrumentation is comparative; it requires a sample of known composition (reference standard) for accurate calibration. These reference standards are produced under stringent manufacturing procedures and differ from laboratory reagents in their certification and the traceability of the data provided.

Potassium Hydrogen Phthalate, Acidimetric Standard, Crystal, Reagent Special, ACS is used in analytical chemistry as a disintegrating agent can be used as a buffering agent (in combination with hydrochloric acid (HCl) or sodium hydroxide (NaOH). As an ACS grade Reagent, Spectrum Chemical manufactured Potassium Hydrogen Sulfate is used as the quality standard against which other Potassium Hydrogen Sulfate substances are graded. it has met the toughest regulatory standards for quality and pureness.

Cannabidiol (CBD), DEA Controlled Substance, 1,000 ug/mLin Methanol While the legalization of cannabis for both medicinal and recreational purposes has been gaining speed, legislation and regulation has not necessarily kept pace. Out of a drive for self-regulation and significant consumer safety concerns, many producers and manufacturers are turning to testing labs in order to ensure that their products are of high quality and free of chemical contaminants.
