Nov 23, 2022 · This document describes best practices for analysis of dissolved organic matter (dissolved organic carbon and total dissolved nitrogen) in seawater samples. Included are SOPs for sample collection and storage, details for laboratory analysis using high temperature combustion analysis on Shimadzu TOC analyzers, and suggestions for best practices in quality control and quality assurance.
Septa are available in a variety of materials and thicknesses. PTFE Natural Rubber are moderately priced seals for GC and HPLC with good chemical properties. They are ideal for multiple injections due to high resealability, but not as easy to penetrate as PTFE/RR. PTFE/High Performance Rubber is a highly pure synthetic red rubber septum that
VOA Vials are made of laboratory quality borosilicate glass as recommended by the EPA. The open top caps are made from a glass reinforced polypropylene resin, and the septa is made from Virgin Teflon® and FDA grade silicone. The Precleaned (2000 class) and QA Analyzed (3000 class) vials are washed
Certified to contain <50 ppb Total Organic Carbon Standard 40 mL septa vial is clear borosilicate glass with 0.125 in. thick, I-CHEM blue, PTFE/silicone septa in an open-top 24-414 polypropylene cap. The I-CHEM molded-in septa retainer ring holds the septa securely in place without
Analytical Vials. Vials play a significant role in analytical analysis and result reproducibility. Vials must be inert and free of extractables or leachables to prevent affecting results. Using certified, application-specific, contaminant-free vials can significantly reduce risk. We offer a broad spectrum of Supelco ® products including
