Weigh, dilute, mix, and more. The work must be done, but it takes up the time of people who could do more valuable work. Method development gets postponed. Data evaluation gets rushed at the end of the day. The queue never quite clears. The MPS robotic smart series can do repetitive work for you. Liquid handling, weighing, mixing, evaporation and centrifugation all run under MAESTRO control, using the same standardised technique every time, on every shift. Your analysts supervise the run and evaluate the data. Discover how automated sample preparation can help you refocus on the tasks that really matter.

Eight hours of bench time. Sixteen hours of a very expensive instrument doing nothing. Most labs are limited by the length of the working day rather than the equipment. The samples are there. The method is validated. The GC-MS is just waiting for the next sample to be loaded. The MPS robotic smart series prepares and injects samples without an analyst present. GERSTEL MAESTRO software schedules the prep steps, and the analysis runs to overlap, so the sequence continues through the evening and into the weekend. You arrive to analyse data instead of a queue.

Vials get a label. However, this is not possible with TD tubes, which is why identifying the tubes is particularly crucial. Just one tube in the wrong place, and the data gets mixed up. In the worst-case scenario, everything must be redone from the beginning. The SID 2 barcode reader reads one- and two-dimensional codes directly on TD tubes, and GERSTEL can supply tubes with the barcode already attached. The code is read and entered the sequence table. Check out how tube tracking works.

Purchase and Disposal costs keep climbing. Additionally, if you suddenly can't get hold of solvents, it becomes a downtime risk rather than a routine. Stir bar sorptive extraction takes the solvent out of the equation. The Twister enriches the analytes directly from the sample, and the enriched analytes are thermally desorbed straight into the GC-MS. Once you've done the conditioning, you can reuse the Twister many times. Check out how solvent-free extraction with the GERSTEL Twister works.

Prep, then analyse. Prep, then analyse. Every minute spent on the bench work is a minute the instrument spends idle. Run them that way and your effective throughput is a fraction of what the system could deliver, no matter how fast the method is. MAESTROs PrepAhead function changes the order of things. Extraction, mixing, evaporation and standard addition for the next samples happen while the current analysis is still running, so the two parts overlap instead of queueing Check out how PrepAhead can speed up your run time.

Preparing a calibration series by hand can take a significant amount of valuable time, so it becomes something you do as rarely as you dare. Furthermore, every manual dilution step has the potential for error. The MPS automatically prepares calibration series, which are set up by the Calibration Standard Wizard in MAESTRO. For thermal desorption, ISDP+ spikes a different volume onto each tube, so a full calibration curve is built. Check out how automated calibration works.
