Toc analyser, microprocessor controlled

  1. 1. Equipment Specification: TOC ANALYSER, MICROPROCESSOR CONTROLLED Version 2 40.052-1/2 40.052 TOC ANALYSER, MICROPROCESSOR CONTROLLED Approval Date: January 2008 Version: 2 Purpose  The TOC Analyser breaks down all the organically bound carbon molecules to single carbon unit that can be measured quantitatively.  To analyse water samples for aggregate carbon content. Conditions and Requirements The instrument shall be compatible with the climatic and other environmental conditions of Indian laboratories. Specifications Description  Microprocessor-controlled analyser with facility for direct measurement of Total Carbon (TC) and Total Organic Carbon (TOC) in aqueous samples and suspensions,and purgeable organic carbon (POC) in samples where purging is possible,having capability for accepting samples containing suspended solids up to 500 m size Method  High temperature catalytic combustion with adjustable temperature range at least up to 900 oC± 2 oC drift  Non-dispersive infrared (NDIR) detector system Result output options  Computer screen  Printer( if not in-built) and facility for printer port  ASCII file transferable to floppy Data processing  Linearisation  Baseline correction  Selection of best calibration curve  Automatic exclusion of anomalous values  Statistical evaluation, like SD, CV Operation and Performance  Measuring range : 1 mg/L to at least 500 mg/L of Carbon  Precision: within 3%  Detection Limit: at least 500 ppb Carbon  Linearity: 1% of calibrated range Power supply  Analyser: 240 volts, 50 Hz  10%  Auto-sampler: 240 volts, 50 Hz  10%
  2. 2. Equipment Specification: TOC ANALYSER, MICROPROCESSOR CONTROLLED Version 2 40.052-2/2 Carrier Gas  Nitrogen or Air of high purity Sample introduction options  Manual loading through sampling boat for samples with high suspended matter(> 100 mg/l), and syringe injection or automatic capillary suction  Automatic with auto-sampler Accessories  Auto-sampler  Micro-litre syringe 250 L and 2500 L  Gas cylinder with purified Nitrogen or Air as recommended with regular(2- stage) and necessary tubings and connectors  Printer (if not provided as in-built)  Operation and maintenance manual in English  Dust cover  Spares and consumables for two years’ operation for each of the following:  Main system  Auto sampler  Printer  Analytical manual including applications for TC ,TOC and POC measurements  Instruction and Service manual with one set of the required tools  Parts catalogue  Application softwares in English  Trouble shooting charts
