SPECTRAL BLENDER
A compact spectrometer system comprising a light source and a spectrometer module and methods of using a spectrometer to determine information related to a property of a mixture are provided. One or more light sources are used to direct light into a mixture. One or more spectrometer modules are used to receive light from a mixture. One or more spectra are measured in response to the received light. A property of the mixture is determined in response to measured spectra.
1 . A method for determining a property of a mixture, the method comprising:
mixing a mixture in a mixing container, the mixing container comprising a housing and a mixing component, wherein the mixing the mixture comprises contacting the mixture with the mixing component as the mixing component moves, wherein the mixing component is separate from the housing and movable independent of the housing;
directing a light from a light source into the mixture in the mixing container;
receiving, at a spectrometer module, a portion of the light directed to the mixture in the mixing container, wherein the spectrometer module is positioned at a separation distance away from the light source; and
determining a property of the mixture in response to the received light.
2 . The method of claim 1 , further comprising:
pouring at least a portion of the mixture out of the mixing container,
wherein the light from the light source is directed into the mixture as the mixture is poured, and the spectrometer module receives the portion of the light from the mixture as the mixture is poured.
3 . The method of claim 1 , further comprising:
positioning the light source and the spectrometer module within the mixing container.
4 . The method of claim 1 , wherein a light blocker is located between the light source and the spectrometer module.
5 .- 9 . (canceled)
10 . The method of claim 1 , wherein the mixing container comprises a light blocker located between the housing of the mixing container and either the light source or the spectrometer module.
11 . The method of claim 1 , wherein the mixing container comprises a diffuser or a reflective element.
12 .- 14 . (canceled)
15 . The method of claim 1 , wherein the light source or the spectrometer module is coupled to a lid of the mixing container through a moveable rod.
16 .- 20 . (canceled)
21 . The method of claim 1 , further comprising measuring a spectrum of the received light and determining the property of the mixture in response to the spectrum.
22 . (canceled)
23 . The method of claim 1 , further comprising calibrating the light source or spectrometer module.
24 . (canceled)
25 . The method of claim 1 , further comprising directing a second light into the mixture, receiving a portion of the second light from the mixture, and measuring a second spectrum of the second received light.
26 . The method of claim 1 , wherein the separation distance of the light is within a range from 5 millimeters (mm) to 30 mm.
27 .- 31 . (canceled)
32 . The method of claim 1 , wherein the light comprises a wavelength within a range from 350 nanometers (nm) to 1100 nm.
33 . (canceled)
34 . The method of claim 1 , further comprising repeating the directing a light into the mixture and the receiving a portion of the light from the mixture one or more times.
35 .- 36 . (canceled)
37 . The method of claim 34 , wherein the directing a light into the mixture and the receiving a portion of the light from the mixture are repeated at a rate of at least 1 per second.
38 .- 39 . (canceled)
40 . The method of claim 1 , further comprising using a sensor to determine a temperature of the mixture or an orientation of the mixing container.
41 . (canceled)
42 . The method of claim 1 , further comprising measuring a property of the mixture selected from the group consisting of: composition, phase, homogeneity, heterogeneity, stability, solubility, uniformity, density, concentration, consistency, particle size, viscosity, dispersion, miscibility, nutrient content, and any combination thereof.
43 .- 91 . (canceled)
92 . The method of claim 1 , wherein the mixing container comprises an annular channel and the light source and the spectrometer are arranged to measure the mixture within the annular channel.
93 . The method of claim 92 , wherein the annular channel is located below the mixing component, and wherein the annular channel is located at a bottom of the mixing container, and wherein the light source directs the light towards the spectrometer module.
94 . The method of claim 92 , wherein the light source is positioned on an inner wall or outer wall of the annular channel, and wherein the spectrometer module is located on an inner wall or outer wall of the annular channel.
95 .- 102 . (canceled)
103 . The method of claim 1 , wherein the directing a light, the receiving a portion of the light, or the determining a property of the mixture occurs during the mixing.
104 .- 120 . (canceled)
