Overview

Most chromatographic or spectrometric investigation processes in the area of instrumental analysis are characterized by the use of autosamplers. The purpose of automation is to increase throughput without the need for additional personnel. Up to now, the samples have been worked through automatically in sequence. This means that with conventional machine control systems, waiting times frequently occur due to sample preparation during which the chromatographs are not used, offering considerable potential for throughput optimization. And it is precisely this potential which is utilized by the new Chronos software. Chronos increases the active measuring time of the machines and therefore considerably raises the efficiency of the laboratory.

The new Chronos software organizes parallel processes for sample preparation. This utilities the analysis system to a much greater extent, while observing the time margins of each individual sample preparation. To this is added further strengths of the software: a user-friendly interface minimizes the number of parameters which need to be changed depending on context. The relevant values are recorded in tabular form and can be changed by the user, which means that a complete sample list can be generated conveniently in only a few steps. Fixed parameters can be changed as needed in the method editor. (Fig.1 Section of window for creating sample lists related to context following selection of method)

A graphic representation of the sample processing is created at the touch of a button, which means that overall duration and current progress can be followed in real time. Multi-stage sample preparation procedures can be parallelized by means of an integrated algorithm. Here also, it is possible to call up a graphic representation of the sequence of events. Chronos also combines the sample list for the autosampler control with the data system list, so that the user only has to administrate one list. This simplifies handling and avoids errors which could be caused by confusing different items.

Chronos is supplied as standard with ready-made modules for the usual analysis procedures; this includes headspace, liquid injection, SPME and other standardized methods such as for example hydrocarbon determination according to DIN H53. If required, the user himself can generate modules in Chronos adapted to his own needs. PAL series autosamplers from the company CTC Analytics and OEM products of the same design are currently supported.

Xcalibur from Thermo Scientific and ChemStation from Agilent are also integrated. Linking of further data systems is in process.

Axel Semrau® has developed this software in cooperation with the University of Bochum. The combination of professional programmers and IT specialists with experienced chemists who have close contact with customers is a guarantee for a practical solution of the very highest quality.

LEAP strives to find total solutions for analytical lab automation by automating analytical processes for small and large molecules in extracted liquids, solids, and recently in human, animal and plant tissues. We provide the precise robotics and efficient sample prep required by modern measurement techniques such as MALDITOF mass spectroscopy. Our newest specialty customization of CTC Analytics’ PAL features small workstations that can perform complex liquid handling tasks including HPLC-Purification, SPE, filtration, weighing, heating and stirring. They can be configured as stand alone units or integrated for “just in time” sample prep for LC-MS or GC-MS analysis.
LEAP provides automated workstation instrumentation solutions based on the LEAP CTC PAL X, Y, Z syringe only autosampler robot from LEAP Technologies. This extremely flexible, precise, and adaptable liquid handling robotic platform is available in a variety of lengths and options depending on the requirements of your sample preparation and injections for your UHPLC, LC or GC chromatography.LEAP offers full support and service for the PAL platform in addition to being able to write custom macros, cycles, and scheduling to your applications. Please contact LEAP Technologies on how we can help you get maximized throughput with flexible pipetting automation solutions.
