Integrated sampler
Organize your run on the instrument itself, with open or closed vials depending on the application.
Direct injection analyzer

FORMACS HT-i is designed for water with particles and suspensions. Its direct injection takes the sample into the combustion furnace to determine carbon and, with the right option, nitrogen.
Capabilities
How the sample is introduced matters as much as the measurement. That is the difference from a system for cleaner water.

TC / TIC
carbon fractions
Total organic carbon is obtained from the total and inorganic fractions. The method defines the preparation.
TN
optional detection
Add the ND25 detector when you need to complement the analysis with total nitrogen.
Handles particles up to 450 µm, or up to 800 µm with the optional wide-bore needle. The concentration and behavior of the suspension must also be evaluated.

The integrated autosampler holds 80 × 8 ml vials. Septumless injection takes the sample directly into the furnace; stirring options help keep the suspension homogeneous. The standard needle handles particles up to 450 µm, and the wide-bore option up to 800 µm.
The sample is analyzed by high-temperature catalytic combustion and NDIR detection. Nitrogen requires the corresponding option.
HTAccess lets you define conditions per sample, follow the carbon and nitrogen signals and add priority samples during the run. It also exports results to Excel or LIMS. The image shows a calibration view.
Applications
Tell us about your sample: what solids it contains, whether they settle and what you need to determine. That information helps us evaluate the instrument against a real case, not just a data sheet.
These are some of the available parameters. Check compatibility with your sample type and analytical method.
Frequently asked questions
FORMACS family video. The image shows HT-i with an add-on nitrogen module; the configuration is defined by application.
Its direct injection and wide-bore needle are especially designed for water with particles and suspensions. HT offers another way to organize water analysis, with an optional autosampler.
The brochure specifies particles up to 450 µm, or up to 800 µm with the optional wide-bore needle. Beyond size, we review their concentration and how they stay in suspension to choose the right configuration.
Nitrogen determination requires the ND25 detector. With the NN reactor it can also determine nitrate + nitrite and calculate TKN by difference: total nitrogen minus nitrate + nitrite.
The type of water, the determinations, the expected concentrations and how many samples you receive. If you have a reference method, include it too.
Yes, with the PRIMACS MCS add-on module for total, inorganic and organic carbon in solid materials. That extension is evaluated separately from the configuration for liquids.
