Abstract
A tissue measurement device can provide for rapid, robust analysis of large volumes of plant tissue samples in the field. The tissue measurement device measures tissue samples in a liquid state. The tissue measurement device uses a spectrometer to determine an absorbance spectrum over a range of wavelengths. The absorbance spectrum provides information about the properties of the tissue sample. Tissue samples may be mixed with various extractants or reagents to further improve the accuracy of measurements or allow measurement of a wider variety of nutrients or properties. The tissue measurement device may also take calibration measurements to improve the measurement of tissue sample properties.
Claims20
A method of measuring a property of a tissue sample comprising:
- mixing a tissue liquid with at least one non-tissue liquid to produce a solution, the tissue liquid originating from the tissue sample;
- illuminating the solution with an ultraviolet-visible light source;
- measuring an absorbance spectrum of the solution with a detector;
- and
- determining the property of the tissue sample based on the absorbance spectrum of the solution.
A method of measuring a property of a tissue sample comprising:
- receiving a tissue liquid originating from the tissue sample;
- illuminating the tissue liquid with an ultraviolet-visible light source;
- measuring an absorbance spectrum of the tissue liquid with a detector;
- and
- determining the property of the tissue sample based on the absorbance spectrum of the solution.
A tissue measurement device for measuring a property of a tissue sample comprising:
- a mixing chamber configured to receive a tissue liquid and at least one non-tissue liquid, the tissue liquid originating from the tissue sample, the mixing chamber configured to mix the tissue liquid and the at least one non-tissue liquid to produce a solution;
- a measurement chamber comprising a ultraviolet-visible light source, and a detector, the measurement chamber configured to receive the solution, to perform a spectroscopic measurement, and to output an absorbance spectrum from the detector;
- a computer configured to receive the absorbance spectrum and to output the property of the tissue sample.
