Optical Spectrometer
What's the difference between using a mass spectrometer vs. a spectrophotometer to analyze food?
I'm learning about spectroscopy and it's applications in food production/analysis
i'm supposed to be focusing on optical analysis so I need to know about spectrophotometers. I'm just not sure when mass spectrometers come into play
it is a quite long storry...
spectrophotometry is relatively good when you deal with a known substance present in substantial quantities
MS is helpful to detrmine something in small quantities or unknown
not all sunstances have characteristic absorption in optical range, often they are masked by other substances
also, MS itself (unlike GC-MS) does not give any idea of concentration, but a pretty good source of information about structures

Miniaturization of the Ion Trap Mass Spectrometer $103.56 The development of miniature ion trap mass spectrometers has been an active area, fueled by the promising analytical capabilities and the convenience of fast in situ analysis. The objective is to miniaturize mass spectrometers in weight, size, and power consumption while retaining the analytical capabilities of mass spectrometry at the same time. The book focuses on the instrumentation of miniature ion trap mass spectrometers, including ionization, ion transfer, mass analyzer, ion detection and related vacuum and electronic techniques. Two miniature mass spectrometers, a 10 kg Mini 10 with electron impact ionization source, developed in 2005 and a 5 kg Mini 11 with multiple ionization sources, developed in 2008, are introduced. The technical details of key components are discussed. Special focus is given to a glow discharge electron impact ionization source, which is an ideal substitute for the filament electron source used in the electron impact ionization, and a discontinuous atmospheric pressure interface, which enables the implementation of atmospheric pressure ionization sources in miniature ion trap mas spectrometers with limited pumping capabilities.

New optical measuring system provides a complete spectrum analysis capabilities
Ocean Optics (OceanOptics) now supplies a new optical measuring system, can be used for LED, lights, flat panel displays, solar radiation and other sources of spectral radiation. New Jaz-ULM-200 small size, has a powerful microprocessor and a low-power display panel. It is easy to use, versatile alternative to the standard optical measurement instrument and the radiation measuring instrument.
Jaz by the superposed-type components, suitable for various uses. Jaz-ULM-200 component containing CCD spectrometer module, a microprocessor with a display panel module, to meet a variety of radiation measurement.
Unlike traditional metering devices, JAZ from the computer, users can access, process and store the complete spectral data. Just press a button three times, stored in the SD card system irradiance measurement software will be collected from the selected light source spectral irradiance complete information. After the subsequent processing of such data, given the strength of selection parameters, including W/cm2, lumens, lux, photosynthetic active radiation (PAR) light intensity or other parameters. System, three key design simplifies operation, even if the operator is not a spectrum expert can be fast, accurate measurements.
In addition to Jaz-ULM-200 spectrometer and microprocessor, it also contains the Ethernet module that allows users to connect through the Internet and JAZ. This network feature can help users to remotely measure, such as remote measurement of solar irradiance, or create a network of multi-point measurements. Ethernet module also comes with SD memory card interface, you can store the data to the SD card. In addition, JAZ can also configure a rechargeable lithium-ion battery module (included SD memory card interface), a portable device to JAZ. Fixed by a special fixture, you can Jaz horizontal, convenient for hand operation.
JAZ Additional system components include a direct connection to the device cosine corrector is used to collect radiation within a 180 ° view; a box with straps and a lined tool box, for placing all the relevant equipment. Software includes system software and Jaz JAZ-A-IRRAD (which is a stored in the SD card radiation measurement applications.)
