一般說明

This substance is listed on the positive list of the EU regulation 10/2011 for plastics intended to come into contact with food.
Triethyl citrate is an ester of citric acid, commonly used as a sequestrant in beverages. It is also reported as an effective plasticizing agent.

應用

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
Triethyl citrate may be used as an analytical standard for the quantification of the analyte in pharmaceutical formulations using high-performance liquid chromatography (HPLC) with UV detection and leaves of Coriandrum sativum and Melia Azedarach medicinal plants using gas chromatography-mass spectrometry (GC-MS).

其他說明

Ion Mobility: TWCCSN2 value of 165.5 Å2 [M+Na]+

The collision cross section (CCS) measurement was provided by Waters Corporation, using the SYNAPT XS mass spectrometer.
For a description and overview of how ion mobility enables the measurement of the CCS of an ion visit ims.waters.com.
Further information on the SYNAPT XS mass spectrometer can be found on the IMS microsite and product webpage.

TWCCS measurements are expected to be within 2% of this reference value.
