Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
Mesityl Oxide may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by gas chromatography-mass spectrometry technique.
These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
These secondary standards offer multi-traceability to the USP, EP and BP primary standards, where they are available.
This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
Ion Mobility: TWCCSN2 value of 119 2 [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.
P/N PHR1547 is part of the Waters Extractables & Leachables UNIFI scientific library which can be downloaded from Waters Marketplace.
