Why spectrophotometers are useful in quantitative color analysis in biochemistry

Since the beginning, Konica Minolta has made state-of-the art measuring instruments that are used across a wide range of industries from manufacturing and food to engineering and medical. Looking specifically at our spectrophotometers, we ll talk a little about how useful they are in the biochemistry field when performing quantitative analysis of color.

Our instruments cannot do the above three paragraphs, for detection of elements or substances you need a much higher resolution and wider wavelength range instrument.

Some examples of what you can do with quantitative color measurement in biochem:

1. Colorimetric assays use reagents that undergo a measurable color change in the presence of the analyte. They are widely used in biochemistry to test for the presence of enzymes. http://en.wikipedia.org/wiki/Colorimetric_analysis

2. Measurement and characterization of proteins by color reactions http://www.sciencedirect.com/science/article/pii/0003269765900606

3. A lot of biological samples status is determined by the color, in the food industry the color of a biological sample (fish, meat, fruit) indicates the freshness which is related the state of the item, as it changes its color changes.

4. Biochemistry color - any method of quantitative chemical analysis in which the concentration or amount of a compound is determined by comparing the colour produced by the reaction of a reagent with both standard and test amounts of the compound, often using a colorimeter. (RK  you can replace colorimeter with spectrophotometer, a spectrophotometer is just a more accurate colorimeter.) Read more: http://www.answers.com/topic/colorimetry#ixzz285mj75AI

Take, for example, our CM-700D spectrophotometer, which accurately measures an object s color through numerous functions that are simple to use. Biochemists appreciate its ergonomic design, which makes it fit comfortably in their hands. The on-screen display shows the operator lots of important information including spectral graphs, pseudocolor and color difference graphs. http://sensing.konicaminolta.us/products/cm-700d-spectrophotometer/

In use, the CM-700D will reproduce measured colors as color patches on the screen, an important function when the operator needs to check the color difference level or search for colors. The instrument features three buttons that can be used for frequent tasks, for example, calling up target colors or menus.

The CM-700D and Konica Minolta s other advanced spectrophotometers are market leaders because of their intuitive design and high level of quality and durability. Although the most cutting-edge technology goes into all of our products, we design them to be very simple to use, even for individuals who are not as tech savvy  as others.

Spectrophotometers used in quantitative analysis are available in both portable and bench top models. We currently offer six bench top models and seven portable hand held models. Each model has certain features that make it ideal for specific projects, and all carry the Konica Minolta stamp of quality and the highest accuracy rate of any spectrophotometers in the industry.



Our CM-700D is an example of a portable instrument that is compatible with Bluetooth, which allows the information it records to be sent wirelessly to a printer or a computer. It has a huge memory that can store 4,000 sets of measurement data and 1,000 sets of target data.

In summary, biochemists find many uses for spectrophotometers when performing quantitative analysis of color. The instruments made by Konica Minolta lead the industry because of their versatility, comfortable design, advanced technology and the greatest accuracy among any other similar devices.
