Description générale

Sodium citrate dibasic sesquihydrate is a colorless crystalline sodium salt.

Application

Sodium citrate dibasic sesquihydrate may be employed in the following studies:
  • In the Supel Que Citrate (EN) tubes for the quantification of pesticides in blackcurrants by triple quadrupole GC-QqQ-MS/MS [Gas chromatography coupled to tandem mass spectrometry (GC-MS/MS) coupled with triple quadrupole (QqQ) analyzer] method.
  • Dispersive solid phase extraction (dSPE) method, commonly referred as QuEChERS.2
  • Preparation of RNA precipitation solution.
