The QP1680 Analyzer measures Total Organic Carbon (TOC) and Total Nitrogen (TNb) in one sample.
The QP1680 is available as a combined TOC and TNb analyzer or for the individual parameters TOC or TNb.
The most important features include:
• Direct sample injection eliminates sample contact with valves and the built-in injection syringe, which minimizes the risk of sample carry-over.
• Large diameter sample aspiration tubing can handle particles up to 800 µm, expanding possible applications and reducing clogging.
• Integrated stirrer for each sample position homogenizes particle-containing samples before injection.
• Small footprint with integrated 65-position auto-sampler requires less space in the laboratory (an auto-sampler with 96 positions is also available as an alternative).
• Simple operation, data analysis and system diagnosis thanks to an intuitive software package.
