In-line filtration

In-line filtration

Every sample for Ion Chromatography analysis must be particle free. This means, almost, every sample needs filtration. While this can be performed manually, that leads to A) a sore thumb and B) a lot of filter cartridges. So let’s automate. Automating sample filtration saves our thumbs and lowers the time...

Low level organic acid analysis

Low level organic acid analysis

Monitoring of individual organic acids with reverse suppression. Monitoring organic acids has been a tricky concept for a long time. As they are weak, to the point of non-dissociated, with a very low conductivity, separation and quantification has always been a headache. Yet monitoring of organic acids is important for...

Monitoring for your Metrohm IC

Monitoring for your Metrohm IC

Keep an eye on your instrument, or let it do so for you! It has been mentioned here before, all instruments need to be looked after. But when should we intervene? With Metrohm IC, all of the primary components are monitored by the system. Columns, pumps and detectors all monitor...

Total N, P and Oxyhalides with one column

Total N, P and Oxyhalides with one column

Total N, P and Oxyhalides: One system, all of the parameters Ion chromatography is the chosen technique for oxy-halide analysis and, with persulfate digestion, quantification of total nitrogen and phosphorus is now simpler with ion chromatography too. While both of these applications are ideal for environmental laboratories, they have required...

Liquid handling, accurate results depend on it

Liquid handling, accurate results depend on it

Accuracy is only a heartbeat away High precision instrumentation is used to improve repeatability and achieve lower detection limits. Ion chromatography certainly falls into this category with some applications achieving detection limits down to 1 ppt. Liquid and sample handling While instruments may be capable of these low detection limits,...

Maintaining your Metrohm IC

Maintaining your Metrohm IC

Care for your instrument, it will love you for it! Like your car, complex laboratory instruments require maintenance. Unlike cars, laboratory instruments cannot run at “near optimal” performance. While your car will keep running if you don’t top up the windscreen washer fluid, an IC will not give the correct...

Flexible analysis for the pharmaceutical industry

Flexible analysis for the pharmaceutical industry

Recent advances in IC applications make it a must for pharmaceutical solutions. Pharmaceutical manufacturing and solution analysis has always been a stronghold of HPLC instrumentation. While HPLC is still the most common technique seen in pharmaceutical laboratories, Ion Chromatography, as a sub-section of liquid chromatography is becoming a very important...

How pure is your lab water?

How pure is your lab water?

You might be surprised at the affect your water and reagents have on instrument operation. Over the course of an analysis, eluent travels through an IC system at a rate of 1,000:1 in comparison to the volume of sample, and that is only when analysing a sample. For this reason,...

MagIC Net: Automated data transfer between your IC software and LIMS

MagIC Net: Automated data transfer between your IC software and LIMS

Tired of entering data in LIMS? We can help with that, it’s MagIC! It has been mentioned here, and in many other places, the number one source of errors in the lab is the person holding the burette, making up the reagents or labelling the vial. This is also true...

Fast analysis for busy laboratories

Fast analysis for busy laboratories

“Chromatography is a slow analytical technique…..” “If it doesn’t use gradient elution it won’t be fast enough……” “I can’t wait that long for results…..” These are all statements that have been synonymous with ion chromatography for a long time, but are they really true? There have been a let of...

Consolidated Beer Analysis

Consolidated beer analysis

For a long time in analytical laboratories, the goal has been automation. Automation removes the human factor from sample preparation and analysis, whether it is 4 am, 11.55 am or 5 pm, sample are handled the same way. The disadvantage of automation has, historically, been each analysis requiring a sample...

Keeping milk fresh, it is a fine line to tread!

Keeping milk fresh, it is a fine line to tread!

Lactoperoxidase process Slowing the lactoperoxidase process is a key way of prolonging the shelf life of milk. Unfortunately, the simple way of doing this, adding thiocyanate to milk, can have a negative effect on the thyroid, especially for infants. Along with iodine and perchlorate, thiocyanate levels in milk have a...
