TOC ANALYSIS TOC and TIC Calibration/QC Standards Certicate of Analysis provided, NIST Traceable, A2LA Accredited, and ISO 9001:2000 Compliant NIST-traceable standards are available for Total Organic Carbon (TOC) and Total Inorganic Carbon (TIC) analyses. A Certicate of Analysis is provided with the standard indicating its lot number and expiration date. TOC and TIC standards are manufactured and veried in accordance with ISO 9000:2001, and analyte concentrations are veried by an ISO 17025 accredited laboratory. Standards for TOC Analysis Matrix: Water 1 mg/L TOC Standard 10 mg/L TOC Standard 25 mg/L TOC Standard 50 mg/L TOC Standard 100 mg/L TOC Standard 250 mg/L TOC Standard 500 mg/L TOC Standard 1,000 mg/L TOC Standard TOC standards are produced from high purity potassium hydrogen phthalate (KHP). Standards for TIC Analysis Matrix: Water OI Analytical Part Number TIC standards are produced from high purity sodium bicarbonate and sodium carbonate salts. Puried reagents, low TOC water (<25 ppb), calibrated Class A glassware, and meticulously cleaned bottles are used in the manufacture of these standards. Balances are calibrated traceable to the NIST in compliance with ANSI/NCSL Z-540-1 and ISO 9001. Publication 30090411 PO Box 9010 College Station, Texas 77842 www.oico.com E-mail [email protected]
