    摘要： A dye binding method for protein analysis is disclosed. The method includes the steps of preparing an initial reference dye solution of unknown concentration from an initial reference dye concentrate and creating an electronic signal based upon the absorbance of the initial reference dye solution. Thereafter, an electronic signal is created based upon the absorbance of a dye filtrate solution prepared from the initial reference dye solution and an initial protein sample. The absorbance signals from the reference dye solution and the dye filtrate solution are sent to a processor that compares the respective absorbances and calculates the protein content of the protein sample based upon the difference between the absorbances. An electronic signal is created based upon the absorbance of a successive dye filtrate solution prepared from the reference dye solution and a successive protein sample, and the absorbance signal from the successive sample dye filtrate solution is sent to the processor to calculate the protein content of the successive sample based upon the difference between the absorbance of the initial reference dye solution and the absorbance of the successive dye filtrate solution.

    摘要： A protein analysis instrument and method are disclosed. The method includes mixing a binding dye composition and a protein sample using a homogenizer, measuring a parameter selected from the group consisting of the speed of the homogenizer and the resistance of the mixture to the homogenizer, adjusting the speed of the homogenizer based upon the measured parameter, pumping unreacted dye composition from the mixture and to a calorimeter, and measuring the absorbance of the dye composition in the calorimeter. Aspects of the invention also include inserting a spout into a sample cup at a position where the spout opening is positioned to avoid foam and precipitate generated by the mixing step and above the bottom of the sample cup and thereafter pumping the dye composition from the mixture in the sample cup through the spout and to a colorimeter.

    摘要： An instrument and associated method are disclosed for the loss-on-drying determination of the volatile content of a wide variety of samples. The instrument includes a cavity in which a sample for which the volatile content is to be determined can be placed, a first source for introducing microwaves into the cavity that have frequencies substantially other than infrared frequencies, a second source for introducing radiant heat into the cavity at frequencies different from the frequencies introduced by the first source, an analytical balance for measuring the weight of a sample while the sample is in the cavity and on the balance, a temperature sensor capable of measuring and positioned to measure the temperature of a sample in the cavity and on the balance, and a processor in communication with the temperature sensor and each of the first and second sources for controlling the introduction of the frequencies of microwave and radiant energy into the cavity in response to the temperatures measured by the temperature sensor to control the sample temperature until the microwaves from the first source and the radiant heat from the second source dry the sample sufficiently for the processor to determine the volatile content of the sample based on the weight change of the sample on the balance.
