Built-In Titrant Standardization Procedures

Users are guided through the standardization of the titrant with methods built into the instrument. titrant concentration is automatically updated after standardization and can also be entered from the Certificate of Analysis (downloadable from www.hach.com) for the specific lot of titrant used.

Automated USEPA-Approved Methods

The AutoCAT automates the USEPA-approved amperometric titration procedures for chlorine, chlorine dioxide, and chlorite determinations as described in “Standard Methods for the Examination of Water and Wastewater.” Sample prepartion is presented to the user in easy-to-understand screen displays. When the titration begins, the process is entirely "hands off."
• Forward titration for free chlorine, 0.1 to 5 mg/L (Standard Method 4500-Cl D. 4b)
• Forward titration for total chlorine, 1.2 µg/L to 5 mg/L (Standard Method 4500-Cl D. 4d)
• Back titration for total chlorine, 5.1 µg/L to 5 mg/L (Standard Method 4500-Cl C.)
• Chlorine dioxide with chlorite, 0.05 to 5 mg/L (Standard Method 4500-ClO2 E.)

Automatic Calculations

In Automatic mode, the endpoint is calculated without user intervention. The AutoCAT 9000 performs a “global least squares regression analysis” to determine the exact endpoint. In Manual mode, you visually inspect the titration curve and select the linear portions of the curve prior to and after the endpoint. The instrument then calculates the exact endpoint.

After the endpoint is determined, concentration is automatically calculated using the titrant concentration, volume of titrant delivered at the endpoint, and the appropriate formula for the selected method. Analyze single or replicate test samples. A running average and the standard deviation of the results will be calculated and archived automatically for replicate tests. The instrument also provides real-time graphics and graphic print output.

The AutoCAT 9000's autoburette precisely controls the titrant delivery. The smallest user-selectable volume increment setting is 0.3 µL and is adjustable. A pre-dose option can be used to speed up titrations—without compromising accuracy—by delivering a large initial volume, and then changing to a small volume increment to assure that enough measurement points are obtained for accurate endpoint determination. Titrant delivery is far more accurate and precise than when performing manual titrations.
