Potassium Iodate (and Iodide)
Potassium Iodate (KIO3) is used commercially in the food industry, primarily as an additive for table salt to prevent a thyroid disease called Goiter. It
Potassium Hydroxide Solutions
Potassium hydroxide (KOH) was discovered by British scientist Sir Humphry Davy in 1807. He used electrolysis to isolate KOH. He later also used this method
Potassium Bromate Standard Solutions
Commercial uses of potassium bromate includes its use in the baking industry, bleaching of dough, and enhancement of the process of rising of the dough.
Perchloric acid 0.1N in Acetic Acid
In pure form, perchloric acid (70%) is potentially dangerous if certain conditions are present. It is an oxidizer, and it is also used to synthesize
Kjeldahl Nitrogen Analysis
This method was developed by Johan Kjeldahl in 1883 for determining nitrogen in both organic and inorganic compounds. Ammonia and ammonium are determined for their
ISO 17034 Accreditation
The ISO 17034 Standard replaced Guide 34 in 2016. It specifies requirements for Certified Reference Material producers (CRM’s). One of these strict requirements is the
ISO/IEC 17025 Accreditation
