The Spectra's
Mass Spectra |
Mass spectrometry is an analytical chemistry technique that helps identify the amount and types of chemicals present in a sample by measuring the mass-to-charge ratio. Vaporised sample will enter the mass spec and become ionised within the ionisation area by firing electrons at the sample. These ions will then all be accelerated to a set speed via magnets and then are allowed to travel across the flight zone where the ions will seperate, the heavier ions will be travelling slower than the lighter ones. The recorder at the end of the mass spec will record at what time and at what mass ions are travelling through. This allows for the sample to be broken down and identified by it's base ions.

Infra-red Specta |
Google definition "Infrared spectroscopy (IR spectroscopy) is the spectroscopy that deals with the infraredregion of the electromagnetic spectrum, that is light with a longer wavelength and lower frequency than visible light. It covers a range of techniques, mostly based on absorptionspectroscopy.".

NMR Spectra |
Google definition "Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy, is a research technique that exploits the magnetic properties of certain atomic nuclei. It determines the physical and chemical properties of atoms or the molecules in which they are contained."
