TOC (Total Organic Carbon) users around the globe requested an instrument that meets the following criteria: simplicity, performance, and durability.

The Lotix TOC combustion analyzer accurately measures carbon content in aqueous matrices down to the ppb level using high-temperature combustion and NDIR detection. Lotix provides cost-effective analysis for wastewater, drinking water, groundwater, seawater, and other challenging matrices.

Lotix supports a wide range of regulatory and industry standards, including:

• Standard Methods 5310B
• EPA 415.3 and 9060A
• ASTM D2579
• ISO 8245
• AOAC 973.47
• EN 13639

Features

• 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 components can be acces​​sed in minutes
• Real-time viewing of analytical data and printing of completed sample reports while instrument is running
• 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

Highly Sen​sitive NDIR Detector​

The Lotix’s NDIR detector is an absolute, non-dis​persive infrared gas analyzer based upon a single path, dual wavelength, infrared detection system. This low-maintenance analyzer is designed for continuous monitoring of CO₂. The Lotix’s NDIR has the following characteristics: 

• High accuracy over the entire measurement range due to automatic temperature and pressure compensation 
• High stability with low zero and span drift 
• 1 ppm signal noise at 370 ppm CO₂ 
• CO₂ measurement range of 0-20,000 ppm without dilution using a single 0.5 mL sample injection. Higher concentrations are achievable with dilution prior to analysis.
