- A spectrophotometer is an instrument that can pass light of a single wavelength through a solution and measure the amount that passes through. First, the spectrophotometer must be zeroed by passing light of the chosen wavelength (500 nm for example) through a blank containing only the solvent. spectrophotometer can be set to measure either the percent transmittance or the absorbance of a solution. In lab, you will be using a spectrophotometer called the Spectronic 20 or Spec 20 to measure absorbance.

What is Spectrophotometer? A spectrophotometer is an instrument which is used to measure the intensity of electromagnetic radiation at different wavelengths. Important features of spectrophotometers are spectral band with and the range of absorption or reflectance measurement.pectrophotometry is a quantitative measurement of the reflection or transmission properties of a material as a function of wavelength. It is more specific than the common term electromagnetic spectroscopy which deals with visible light near ultraviolet and near infra-red.

How to use tensiometers Tensiometers can also be used to determine the effectiveness of rainfall, the need for winter irrigation, and help in problem solving where run-off, water logging or poor water distribution occur. In areas where supplementary irrigation is used, tensiometer readings will assist to determine when and how much to irrigate, without wasting a precious storage.

What is a Potentiometer Used for? Potentiometers are a form of electrical resistors. While not designed to carry a great deal of electrical current, they are often ideal for small jobs. A potentiometer is helpful in such common tasks as adjusting the volume level on a radio, or changing channels on some types of television sets.

- Mass Spectrometry Applications. Mass spectrometry (MS) measures the mass-to-charge ratio of ions to identify and quantify molecules in simple and complex mixtures. MS has become invaluable across a broad range of fields and applications, including proteomics.he broad scope of proteomics has only begun to be realized within the last 15 years due in large part to technological developments in mass spectrometry. Mass spectrometry is a sensitive technique used to detect, identify and quantitate molecules based on their mass and charge (m/z).

What is NMR? Uses of NMR spectroscopy. Nuclear Magnetic Resonance (NMR) spectroscopy is an analytical chemistry technique used in quality control and reserach for determining the content and purity of a sample as well as its molecular structure.For example, NMR can quantitatively analyze mixtures containing known compounds.he basis of NMR. The principle behind NMR is that many nuclei have spin and all nuclei are electrically charged. If an external magnetic field is applied, an energy transfer is possible between the base energy to a higher energy level (generally a single energy gap).

- No, not in light sabers! For one thing, lasers can be used in a device called a spectrometer. A spectrometer uses light to identify the chemical composition of matter. For example, as light passes through a gas, the gas soaks up certain colors, or wavelengths, of light. Different gases absorb different wavelengths.irst, the light from a laser contains exactly one color or wavelength rather than a lot of different wavelengths. Scientists say that laser light is  monochromatic , meaning of one color. Flash is required to view this animation. Second, all the wavelengths are in phase.
