General description

The buffer solution (citric acid/sodium hydroxide/hydrogen chloride) is gravimetrically prepared using high-quality reagents in high-purity water. It is quality controlled and qualified in an ISO/IEC 17025 accredited calibration lab. Its pH value of 4.00 at 20°C is qualified using a combined glass electrode following a 5-point calibration method, in accordance with DIN 19268, against certified primary reference standards as per DIN 19266, IUPAC, NIST, USP, and Ph. Eur.
