Advantages of the Man-Tech AutoMax™ Samplers

Disadvantages of Carousel Autosamplers |
Man-Tech AutoMax™ robotic sampler probes move directly to the samples, while the sample cups remain stationary. |
With a carousel autosampler, the sample cups have to move to set positions where the probes can reach them. This requires extra move steps with 5 very important considerations, all of which may fail::
These extra move steps, especially with a heavy tray full of samples, add to wear and tear on the carousel sampler. |
Man-Tech AutoMax™ robotic samplers allow the entire travel area to be used for sample positions, allowing large sample capacities. It is very simple to ensure that travel is over previously analyzed samples or between sample rows, eliminating cross-contamination. When a value is determined for the number of sample positions versus footprint, the AutoMax™ samplers offer the best value for laboratories. An X,Y rack with an identical number of samples per row, is logical and easier to use on a daily basis. |
Carousel autosamplers require concentric, side-by-side rows of samples to increase capacity, requiring careful programming to ensure travel of probes does not occur over un-analyzed samples. Also, the concentric rows contain different numbers of samples as the circle diameter gets smaller approaching the center. This is more difficult to use compared to an X,Y rack with an identical number of samples per row |
Man-Tech AutoMax™ samplers enable simple definition of rack positions for calibrants, QC, standards, etc. as well as easy addition of rush/priority samples. Travel to and from these sites will be over previously analyzed samples or
between rows, thereby eliminating any potential for cross-contamination. |
Some carousel autosamplers may allow for these set positions, but in some cases it will require travel over un-analyzed samples, leading to cross-contamination. These extra movements also add to the wear and tear on the autosampler. |
Man-Tech has over 39 years of automation experience utilizing X, Y, Z and carousel autosamplers in different instrument configurations. The decision to employ X, Y and Z autosamplers was made specifically to enhance the value for laboratories. |
