Chemistry
| Oxidation by Combustion: From 680 °C - 1000 °C
|
TOC Detector
| Nondispersive Infrared (NDIR) with Static Pressure Concentration (SPC) – Patented
|
TOC Analytical Modes
| TOC (NPOC), TC-IC, TC, IC
|
TOC Analytical
| Limit of Detection: 50 ppb
Maximum Measurable Concentration: 30,000ppm
Carryover: ≤ 1.0% Cross Contamination
Sample Size: 100 µL to 2.0 mL
Precision*: ≤1.5% RSD, ±15 ppb, typical of a mid range standard (Whichever is greater over seven replicates).**
* Analytical performance is affected by laboratory water, reagent and gas purity, sample container cleanliness, sample matrix, gas
regulator cleanliness and precision, and operator skill.
** %RSD Area, as opposed to %CV, calculates precision after blank subtraction. This yields a lower precision measurement, but
improves sensitivity and accuracy.
|
TOC Analysis Time
| 6-10 minutes typical for TOC analysis: 29 minutes typical for triplicate TOC analysis
|
Carrier Gas Handling:
| Mass Flow Controller for instant control of carrier gas (0-500 mL/min). Automatic Leak Check capability
|
Liquid Handling
| Syringe driver, 7-port distribution valve. Auto-dilution capability for higher TOC concentrations and difficult matrixes.
Self-cleaning sample handling process that cleans injection line on every repetition.
|
Liquid Handling
| Integrated Autosampler
|
Controller
| PC, Interface through Windows™ 7 or greater
|

TOC Utility Requirements
| Voltage: 100/120/240 VAC (±10%) factory configured
Frequency: 50/60 Hz, Power: 1200VA
|
TOC Dimensions
| 18” W x 24.5” D x 32” H, Shipping weight 147 lbs
|
TOC Gas Supply
| Hydrocarbon and Carbon Dioxide (CO2) free air (with greater than 18% oxygen) with TOC content <1ppm or UHP O2. Gas can be
supplied from a cylinder or TOC gas generator. If a TOC gas generator is used, resulting gas must be hydrocarbon and water free. To
assure clean carrier gas is used, we suggest employing a complete CO2
removal system and hydrocarbon trap between the gas source
and analytical instrument.
