Interference Check Standard #18, HNO3
Description
Interference Check Standard # 18 is a kit of two solutions with Silver separated from the other elements for stability. Interference check standards are used to verify and optimize interference correction settings in ICP spectrometry. For sequential ICP instruments, they help confirm that appropriate background correction intervals have been established. For simultaneous ICP instruments, they are used to verify proper inter-element correction factors. These standards are suitable for use with U.S. EPA Method 200.7, Revision 4.4, and SW-846 Method 6010, Third Edition.
CPI International's Peak Performance Multi Element standards are produced in a controlled environment using ultra high-purity starting materials with NIST traceability and with ISO 17025 and ISO 17034 accordance. Each standard is verified instrumentally and gravimetrically and comes with a Certificate of Analysis and an SDS is available to download at sds.cpiinternational.com. CPI guarantees the accuracy of our stock Peak Performance Single-Element standards to +/- 0.5% with a 30 month shelf life from manufacture date and an 18 month period of validity.
