Ultimate flexibility

With your 940 Professional IC Vario, you are ready to meet any analytical challenge in ion chromatography.

Regardless of which parameters you need to determine and the properties of the sample matrix – the right sample preparation, the right detector, and the right extension for liquid handling, suppression, or neutralization are available based on a comprehensive modular system.

Expand your system as you need it

Your 940 Professional IC Vario system can be adapted and/or expanded at any time with various extension modules as well as with other upgrade options, e.g., for inline eleuent preparation or multi-channel analysis. Hence, you can set up an AnCat system and determine the complete ionic content of your samples in a single run.

Superior reliability – we call it "intelligent ion chromatography"

Working with your 940 Professional IC Vario is like having an invisible assistant by your side. System monitoring functions make sure that

  • all system and method parameters are checked against any limit values
  • instruments and their functional parameters are checked and integrated in the method
  • results are monitored and can be traced back to every single step of the analysis
If any parameter exceeds a defined limit, your 940 Professional IC Vario sends you a message – in plain text.

Simply add water – inline eluent preparation

Combine your 940 Professional IC Vario with the 941 Eluent Production Module and you can produce eluents of any composition and concentration (including organic modifiers) – inline, and even from ordinary tap water, if you connect an ultrapure water system.

Automated inline eluent preparation

  • ensures stable retention times
  • contamination-free working
  • saves manual working steps
Up to four eluents can be mixed, depending on the application!

Choose any column you need

With your 940 Professional IC Vario system you are free to choose any analytical separation column you need and want.

You can select columns with different base materials, selectivities, capacities, and dimensions. Apart from columns with a 4 mm inner diameter, you can also use 2 mm columns to reduce eluent consumption.

Run any gradient you need

Various gradient options are available in the 940 Professional IC Vario system, depending on your analytical requirements: high-pressure gradient, low-pressure gradient, and Dose-in Gradient. Gradients are a proven way to speed up your analyses.

STREAM – the green way of suppression

STREAM (Suppressor Treatment with Reused Eluent After Measuring) uses the suppressed eluent for rinsing the regenerated suppressor unit after the detection step.

With STREAM, you need fewer chemicals and produce less liquid waste. Moreover, STREAM enables non-stop system operation for at least two weeks – and even longer, if you rely on inline preparation of the regenerant.

Challenging matrices? Easy with Metrohm Inline Sample Preparation!

Suspensions, samples loaded with proteins, or heavily contaminated wastewater put a challenge to any kind of chromatography.

Metrohm Inline Sample Preparation helps you to deal with even the most difficult matrices for straightforward analysis on your Metrohm IC.

Automation – higher throughput, better results

You can use the full scope of Metrohm automation to boost sample throughput and the quality of results on your 940 Professional IC Vario.

Whatever number of samples you want to analyze, whether they need cooling or any particular kind of liquid handling, we can provide an automated solution for everything.

Intelligent injection techniques for an extended working range

Your 940 Professional IC Vario can be combined with various intelligent injection techniques.

Think of these techniques as automated high-precision liquid handling that makes working with your IC more efficient while increasing accuracy and reliability of your results.

"MiPT" Metrohm intelligent Partial-Loop Injection, e. g., uses a variable injection volume to cover a sample measuring range that extends across 4 orders of magnitude. This means that samples in the range of 10 μg/L to 100 mg/L can be analyzed with a single calibration!

MagIC Net – the proven Metrohm ion chromatography software

Your 940 Professional IC Vario system is controlled by MagIC Net, the proven Metrohm Software for ion chromatography.

MagIC Net also controls any peripheral modules for liquid handling and automation. MagIC Net records the results produced, enables modern data management and reporting as required by the user. Learn more about the benefits of MagIC Net here.
