Sr. Instrument /accessory Component Specifications No description TOC/TN analyzer. The system should include TOC analyzer for solid and liquid samples, with NDIR detector and Pt catalyst, with halide scrubber and moisture traps, TN analyzing unit based on chemiluminiscence, auto sampling unit and the system should be upgradable to solid sample analyses. The instrument should simultaneously and/or stand alone measure TOC and TN in sediment samples (marine, lake and terrestrial) and water samples controlled with software .PC 1 TOC analyzer unit NDIR detector based analyzer, PC controlled, High temperature oxidation, aqueous samples Measured parameters IC: Reproducibility: ± 1.5%. Measuring range 0-3000 ppm. Detection limit: ± 5 ppb. TC & NPOC: Reproducibility: ± 1.5%. Measuring range 0-3000 ppm. Detection limit: ± 50 ppb. Multiple units (ppm, µg/L)* 2 TN analyzer unit Chemiluminiscence based detector; with provision for simultaneous TN measurements Measured parameters TN: Reproducibility: ± 3%. Measuring range 0-3000 ppm. Detection limit: ± 25 ppb. 3 Working temperature range 10 35C – 4 Sample analyses time < 7 mins. 5 Sample injection and maximum injection Automatic; < 500 µL volume 6 Acidification for IC removal Automatic (including sparging) 7 Sample dilution and dilution accuracy Automatic dilution range 2x to 50x (± 5%) 8 Data processing Linearization, peak detection, calibration, area calculation, SD and CV calculation, automatic reanalyses of samples depending upon dilution requirement 9 Instrument Controls Aspiration, measurement, injection, volume setting, Turning on/off of carrier gas, self diagnostics, warning for abnormalities, leakage timer for restarting from running conditions, Automatic blank checks and correction, Multipoint calibration, Baseline autocorrection, Automatic power shut down after furnace cooling. 10 Additional essential features High-salt sample combustion tube kit, Halogen scrubber, gas sample injection kit, POC measuring kit with sparger. 11 Automatic Sample Injection (ASI) unit Vial capacity: 20-30ml; 40 ml and more Vial capacity: 90 and 65
