• No costly syringe drives or 7-port valves!
  • Ability to run 0-20,000 ppm without dilution with a single 0.5 mL injection volume virtually eliminating the need for multiple calibration curves
  • Easy to use software requiring < 1 minute to set up a calibration curve
  • Simple design ensures virtually any component can be accessed in minutes, and with the furnace located in the front, combustion tube maintenance is a snap
  • Real-time viewing of analytical data and printing of completed sample reports while instrument is running
  • Easy scheduling of priority samples
  • Ability to export to CSV or PDF and import from CSV files
  • Average run time for triplicate TOC is 13-15 minutes (depending on concentration)
  • Uses a pressurized 10 L water reservoir to clean the sample pathway, loop and needle before and after each sample without using any positions on the autosampler​

Options

  • Mixing Module - The optional Lotix Mixing Module is designed to stir samples in the vial prior to analysis. The mixing module contains a magnet attached to an electric motor. The rotating magnet in the module causes a magnetized stir bar in the vial to rotate and mix the sample.
  • SO3 Scrubber - Certain sample matrices (such as samples preserved with sulfuric acid) have the potential to create gases harmful to the Lotix NDIR detector during analysis. The optional Lotix Sulfite (SO3) Scrubber (mistcatcher) removes these gases before they reach the detector.
  • Salt Analysis Kit - The Salt Analysis Kit contains required components for the analysis of sea water and brines on the Lotix TOC analyzer. The kit includes a 0.3 mL sample loop, large sphere catalyst and combustion tube, and replacement parts for Lotix components whose life-span is reduced when analyzing this sample type.​​​​​

​Chemistry
 ​​Oxidation by Catalytic Combustion: From 680 °C - 1000 °C
​TOC Detector
 ​Non-Dispersive Infrared (NDIR) Detector
​TOC Analytical Modes
 ​TOC (NPOC), TC-IC, TC, IC
​TOC Analytical
 ​Concentration range 0-20,000 ppm without dilution using a single 0.5 mL sample injection. Higher concentrations achievable with dilution prior to analysis.
Limit of Detection: 50 ppb
Carryover: ≤ 1.0% Cross Contamination
Sample Size: 0.5 mL (0.3 mL for high concentration, difficult or salt samples)
Precision*: ≤ 2% RSD, typical of a mid-range standard.

* Analytical performance is affected by laboratory water, reagent and gas purity, sample container cleanliness, sample matrix, gas regulator cleanliness, 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
 ​13-15 minutes typical for triplicate TOC analysis
​Carrier Gas Handling
 ​Integrated pressure regulator with in-line flow restrictors to maintain carrier gas at 200 mL/min
​Liquid Handling:
 ​Pressurized sample delivery and liquid handling
Solenoid actuated micro-pump precisely delivers acid for IC removal/analysis in 50 µL increments +/-5%
Self-cleaning sample handling process that cleans sample pathway before and after every sample 
​Sample Introduction:
 ​Integrated 30-position autosampler
​Controller
 ​PC, Interface through Windows® 7 or greater
​Data Handling
 ​Reports exportable to CSV and PDF format
Importing from CSV file
Real time viewing and printing of analytical results while instrument is running
Ability to store customized individual test methods
Priority samples via schedule interrupt
Outlier deletions and precision performance criteria controls
​Other Features
 ​Pre-programmed point and click method set-up
Instrument condition light
Automatic and configurable standby mode
Simple design ensures access to internal components in minutes
Combustion tube can be accessed from the front of the instrument in minutes
Autorinsing from sample and/or rinse water via built-in rinse station
​Principal Applications
 Wastewater, Industrial Waste Effluent, Surface Water, Ground Water, Sea Water​
​Methods
 ​Standard Method 5310B, EPA 415.1, EPA 9060A, ASTM D2579, ISO 8245, AOAC 973.47
​Certification
 ​CE (CSA site certified if required)
​TOC Utility Requirements
 ​Universal Voltage: 100/115/230 VAC (±10%)
Frequency: 50/60 Hz, Power: 1150 VA
​TOC Dimensions
 ​18.2” W (46.2 cm) x 23.7” D (60.2 cm) x 26.3” (66.8 cm) H (Lotix only) Weight 53 lbs (24 kg) (Lotix only)
​TOC Gas Supply
 ​Hydrocarbon and Carbon Dioxide (CO2) free air with (greater than 18% oxygen) TOC content <1 ppm 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. Ultra-zero air or Oxygen may be used.
​TOC Gas Inlet Pressure​​
 ​50 to 100 psi
