ZSX Primus / SSLS
Smart Sample Loading System
Rigaku’s new Smart Sample Loading System (SSLS) adds a new dimension of flexibility to the ZSX Primus WDXRF spectrometer. For sample types that are amenable to such a process, a vacuum chuck can be used to load samples into pre-loaded sample holders. This sample loading system has two important consequences: time is saved by the operator since they are no longer required to manually load each sample in a sample cup and the number of samples that can be held on the sample deck is increased significantly
Permissible sample types
Rigaku’s SSLS can handle samples up to 50 grams in weight and the modular sample deck racks have been designed for different sample diameters. Samples with a diameter of 35 mm can be stored 32 samples to a rack with three such racks sitting on the deck. Samples with a diameter of 40 mm can be stored 24 samples to a rack with a possibility of three of these racks on the deck. In addition, the racks can be mixed so that different sample sizes are easily accommodated on the deck at the same time. Sample types that are amenable to this type of loading procedure include fused glass beads and pressed powders. Both plastic and metal pressed powder holders are permitted.
A precision vacuum chuck is used to safely and reproducibly pick up the samples and place them in the measurement sample holder. Each sample type has a specific sizing ring positioned in the measurement sample holders to assure that the sample is properly positioned for measurement, and the analytical reading surface is never compromised.
Keeping track of samples has never been easier. A two-dimensional barcode can be attached to the non-analysis surface of each sample. Before the sample is lowered into the pre-evacuation chamber through the input port, the barcode is scanned and the sample information is loaded into the control software.
