Mettler Toledo has launched version 2.0 of its LiQC multi-parameter system for simultaneous determination of density, refractive index, pH/conductivity and colour.
LiQC increases productivity by combining single measurements into one fully automated process.
A sample is filled into a sample vial, placed onto an automatic sample changer and assigned a barcode label.
LiQC then automatically completes every subsequent step: choosing the appropriate method, pumping the sample into the various flow-through cells and performing all measurements.
The results are statistically evaluated, compared to specifications and transferred to LIMS systems.
It then thoroughly cleans and dries the measuring cells simultaneously before moving on to the next sample.
Version 2.0 brings other benefits: biometric user identification with a fingerprint reader greatly eases user management, which is a prerequisite for analysis in compliance with 21CFR-11 or ISO17025 standards.
Additionally, LiQC now works with stand-alone density and refractometers as well as with DR combined meters, so the system may be used for density and colour measurement of lubricants or for pH and Brix measurement of fruit juice.
LiQC brings substantial time savings, simplified compliance and easy LIMS integration for analytical laboratories in many different industries.
It is particularly suitable for the flavour and fragrance, petrochemical, beverage and pharmaceutical industries, where multi-parameter measurements are performed for identification, purity and concentration determinations and by independent testing laboratories that have to deal with a large quantity of samples and very short turnaround times.
