multi N/C 4300 Series The Trace Detector
- Optimum sensitivity at TOC trace levels
- Short measuring times and highest oxidation power due to high-energy UV radiation at 2 wavelengths
- Economical operation thanks to long-lasting components and inexpensive reagents
- Time-saving automation functions for the ultrapure water range
- New intuitive software with live result display
An extremely sensitive and precise UV digestion device, which is ideally suited for ultra-pure water analysis - in the trace range even without persulfate.
TOC trace analysis without oxidizing agents
The highly precise multi N/C 4300 UV is specifically designed for TOC analysis at the ultra-trace level. He is ideal for analyzing boiler feed water in large-scale power plants, water for injection purposes and TOC cleaning validation in the pharmaceutical sector. Equipped with a high-performance UV reactor, all carbon compounds can be digested rapidly and completely, even in difficult matrices such as monitoring of electrolysis baths for electroplating. At the ultra-trace level, the UV reactor enables digestion without persulfate, which makes operation more efficient, avoiding TOC blank interferences. The device can be retrofitted with a solids module for non-catalytic high-temperature combustion.
- TOC analysis at the ultra-trace level thanks to maximum injection volumes of up to 20 mL
- Persulfate-free sample digestion thanks to high-power long-life UV reactor
- High NPOC sample throughput due to parallel purging and measurement
- New intuitive software with live result display and 21 CFR Part 11 compliant pharma module
- Significant time savings thanks to long-term stable calibrations
- Automatic acidification, purging and sample homogenization
- Device can be upgraded for TOC analysis of solids by means of non-catalytic high-temperature combustion
- Five-year warranty for the focus radiation NDIR detector and three-year warranty for the UV reactor
High performance for wet chemical UV digestion
TOC analysis at the ultra-trace level requires precision and efficiency. Flow injection from the syringe pump combined with the focus radiation NDIR detector enables a low detection limit of 1 µg/L C at the ultra-trace level.
Sample digestion is performed using a long-life high-power UV reactor with two oxidation wavelengths. The particularly high-energy UV radiation at 254 nm and 185 nm oxidizes even extremely stable carbon compounds quickly and completely, and this without any oxidizing agents such as persulfate. Not only does this make operation safer and more economical, it also delivers more accurate results as it avoids distortion of measurement results due to reagent blank values.
The highly sensitive FR NDIR detector, combined with the high radiation intensity of the UV reactor, makes for precise CO2 detection at the trace and ultra-trace level and also makes the device suitable for aggressive matrices.
The Easy Cal function enables stable long-term multi-point calibration from a single stock solution, saving time and effort.
The automation solutions are specifically designed for applications at the ultra-trace level, making sample preparation and analysis more efficient, and they can be tailored to the needs of our customers. Our comprehensive autosampler portfolio enables automatic acidification, parallel purging and magnetic stirring to homogenize samples, as well as external needle rinsing to prevent sample carryover. The EPA sampler allows operation with polymer septa for TOC analysis in ultrapure water. Optimum blank value minimization is achieved by permanent purging of reagents.
TOC solids measurement can be configured using the additional module HT 1300, which offers manual sample introduction via ceramic boats. This is used for non-catalytic high-temperature combustion at up to 1800 °C (with additives) in a ceramic combustion tube.
Manual TIC analysis for solids by direct acid digestion is available with the TIC module.
