Abstract: What is disclosed is a method for creating a database for determining a virtual reference value for a light transmission aggregometry measurement, comprising the following steps: a. providing platelet-rich plasma “PRP” (17) of a reference blood sample; b. performing a light transmission measurement with a first light wavelength and a second light wavelength (14), different from the first, on the PRP (17) of the reference blood sample; c. providing platelet-poor plasma “PPP” of the reference blood sample; d. performing a light transmission measurement on the PPP in order to determine a PPP reference value; e. assigning the measurement result of step d to the measurement results of step b in a database; f. repeating steps a to e for a plurality of reference blood samples. The database obtained using this method makes it possible to determine a virtual reference value that is an excellent estimate of the PPP reference value.

Abstract: Embodiments described herein may be useful in the detection of analytes. The systems and methods may allow for a relatively simple and rapid way for detecting analytes such as chemical and/or biological analytes and may be useful in numerous applications including sensing, food manufacturing, medical diagnostics, performance materials, dynamic lenses, water monitoring, environmental monitoring, detection of proteins, detection of DNA, among other applications. For example, the systems and methods described herein may be used for determining the presence of a contaminant such as bacteria (e.g., detecting pathogenic bacteria in food and water samples which helps to prevent widespread infection, illness, and even death). Advantageously, the systems and methods described herein may not have the drawbacks in current detection technologies including, for example, relatively high costs, long enrichment steps and analysis times, and/or the need for extensive user training.

Abstract: An automated computer-controlled sampling system and related methods for collecting, processing, and analyzing agricultural samples for various chemical properties such as plant available nutrients. The sampling system allows multiple samples to be processed and analyzed for different analytes or chemical properties in a simultaneous concurrent or semi-concurrent manner. Advantageously, the system can process soil samples in the “as collected” condition without drying or grinding. The system generally includes a sample preparation sub-system which receives soil samples collected by a probe collection sub-system and produces a slurry (i.e. mixture of soil, vegetation, and/or manure and water), and a chemical analysis sub-system which processes the prepared slurry samples for quantifying multiple analytes and/or chemical properties of the sample. The sample preparation and chemical analysis sub-systems can be used to analyze soil, vegetation, and/or manure samples.
