Laboratory automation
Chromtech
The single magnet mixer (SMM) from Chromtech automatically stirs and tempers samples. It is available for PAL3 RTC and RSI from CTC Analytics as well as for the older PAL-classic generation.
Stirring and tempering
The Single Magnet Mixer (SMM) stirs the sample with a small magnetic stir bar in the vial. A stepper motor drives the stirring process; heating and stirring are controlled by PAL3 and any PAL control software. Speed and direction of rotation can be selected, including alternating directions.
SPME means solid phase microextraction; SPME Arrow uses a larger extraction element. SPDE refers to dynamic solid phase extraction. Headspace is the analysis of the gas space over a sample. The attainable temperature depends on the design and operating conditions.

While the SMM stirs and controls the sample temperature, SP400 conditions the SPME fiber after extraction and desorption. SP400 complements the automated workflow as a Chromtech PAL3 option and is also available for older PAL systems.
SP400 – condition SPME fibers →Application Notes
BTEX in water was repeatedly extracted via a PDMS fiber using the Single Magnet Mixer. After taking into account the expected sample removal, the relative standard deviations of the investigated components were between 0.75 and 1.12 percent.
0,75–1,12 % relative standard deviationOpen English PDFA beer sample mixed with BTEX was examined by SPME with SMM and agitator. For several higher-boiling components, the SMM showed better reproducibility and on average around 15 percent more signal.
Around 15% more signal on averageOpen English PDFTerms: SPME refers to solid phase microextraction. BTEX represents benzene, toluene, ethylbenzene and xylenes. The relative standard deviation describes the variance of repeated measurements in relation to the mean value.
