CTech™ SoloVPE® PLUS System User Guide
Sample Vessel: The component of the SoloVPE PLUS System that holds the sample to be measured. There are different sizes
(volumes) of sample vessels and materials (fused silica and UV plastic).
Sample Vessel Holder: The component of the SoloVPE PLUS System that properly secures the sample vessel in the instrument in
preparation for measurement. Sample vessel holders come in different configurations to match the style of sample vessel being
used (micro/small and large).
Slope Spectroscopy: An analytical technique based upon the Beer-Lambert law, which utilizes the slope term of a statistically
analyzed absorbance vs. pathlength plot to make calculations and predictions of sample properties.
Solo Validation Cuvette Adapter: The SVCA is an optional accessory that provides an additional technique for validating the SoloVPE
PLUS device and specifically allows the use of filters and standards based on a cuvette form factor.
SoloVPE PLUS (Variable Pathlength Extension): The variable pathlength instrument that enables Slope Spectroscopy measurement
methods.
Threshold: A user-specified limit specified in absorbance units (AU) that the SoloVPE PLUS system will scan the pathlength range to
find, if possible.
Zero Pathlength: The position the system drives down to prepare the SoloVPE PLUS and Fibrette Optical Component for data
acquisition. When in this position, the Fibrette tip is in contact with the bottom of the sample vessel. All pathlength parameters and
motions are referenced from this position, which corresponds to a pathlength of zero millimeters. Also referred to as Zero Position
and Fixed Zero.
