total organic carbon
Total organic carbon
Determine the organic carbon content of your samples with the right method for your type of water.
FORMACS HT
Carbon analyzer for liquids
Carbon analysis.
At your own pace.
From a single sample to a full run, FORMACS HT lets you organize carbon analysis in water with the level of automation you need.
- Principle
- Catalytic combustion
- Carbon detection
- Non-dispersive infrared (NDIR)
- Operation
- Stand-alone or with autosampler
Capabilities
Start with your routine.
Choose how to automate it.
Not every lab receives the same samples or works at the same pace. The configuration should reflect those differences.
NPOC
automated preparation
Acidification and sparging
Program acidification and sparging to prepare the sample before measurement.
TN
expansion option
Total nitrogen
If you also need total nitrogen, you can add the matching detection.
The autosampler, nitrogen detection and solids module are options chosen separately.

04 / Results
01Sample introductionManual or automated operation.
Introduce samples one at a time or add the autosampler to process runs. The choice depends on how your lab is organized.
02PreparationDefined by the method.
For NPOC, the instrument acidifies and sparges the sample automatically. With the dual needle set-up, it can prepare the next sample while analyzing the current one. This helps reduce waiting time between samples.
03CombustionCarbon conversion.
Carbon is converted to carbon dioxide by high-temperature catalytic combustion, then measured by non-dispersive infrared.
04ResultsControl with HTAccess.
HTAccess lets you assign analysis conditions per sample, prepare standards and manage dilutions. You can add priority samples during the run and export results to Excel or to your laboratory information management system (LIMS).
Applications
From drinking water
to process water.
What water does your lab analyze? The sample type and expected concentration help us choose the right method and preparation.
- TC — Total carbon
- IC — Inorganic carbon
- TOC — Total organic carbon
- NPOC — Non-purgeable organic carbon
- DOC — Dissolved organic carbon
- POC — Purgeable organic carbon (optional)
- TN — Total nitrogen (optional)
- Nitrate + nitrite — With NN reactor and nitrogen detector
- TKN — Calculated by difference, with TN + NN configuration
These are some of the available parameters. Check compatibility with your sample type and analytical method.
Frequently asked questions
Before you choose
your FORMACS HT.
Do I need an autosampler from the start?
No. FORMACS HT can work as a stand-alone analyzer. If you process samples in batches, the optional autosampler automates sample introduction.
When is HT-i a better choice than HT?
HT-i is especially designed for water with particles and suspensions. If your samples have these characteristics, we review their compatibility with you before you choose.
Can I extend the instrument to analyze solids?
Yes, with the PRIMACS MCS add-on module. It is an extension for carbon analysis in solids and is not part of the basic instrument for liquids.
What should I share to choose the configuration?
The type of water, the determinations you need and your daily workload. It also helps to know the method you use today and which part of the work you want to automate.
How does it determine Total Kjeldahl Nitrogen (TKN)?
With the nitrogen detector and the NN reactor, it measures total nitrogen and nitrate + nitrite, then calculates TKN by difference. It is an instrumental alternative: check that it is accepted under the method your lab uses.
