three parts: Far infrared -1mm to 10µm Mid infrared - 10µm to 2.5µm Near infrared - 2.5µm to 750 nm Infrared (IR) Spectrum: Infrared (IR) Spectrum IRGAS System mid infrared range 2.5µm – 25µm in wavelength 4000 cm-1 – 400 cm-1 in wavenumbers Wavelength (λ) Wavelength = (1/wavenumber)*10,000 Wavenumber (cm-1) Wavenumber = (1/λ)*10,000IR Molecules : IR Molecules Not every molecule absorbs infrared light Monoatomic He, Ar, Ne, etc… Homoatomic diatomic N2, O2, H2, etc… N N Molecules that do absorb infrared light Water is a good example O H H Michelson Interferometer: Michelson Interferometer Step 1: Beam leaves IR source and hits beamsplitter where it is sent straight through and at a 90° angle Step 2: The 90° angle beam hits a fixed mirror and is sent back to the beamsplitter Step 3: The beam that went straight through hits a movable mirror and is sent back to beamsplitter Step 4: The two beams recombine, go through the gas cell and travel to the detector 1 2 3 4Michelson Interferometer: Michelson Interferometer When AB=AC the phase of the frequencies look the same When AB=AC+1/4λ, then the phase of the frequencies are opposite in regards to maximums and minimumsMichelson Interferometer: Michelson Interferometer When AB=AC and the two recombine you get stronger maximums and minimums When AB=AC+1/4λ and the two recombine they cancel one another out and result in a flat line ABB Bomem Michelson Interferometer: ABB Bomem Michelson Interferometer It has two sets of mirrors that move by a pivoting motion This design is called a wishbone configuration This configuration is more robust It can be placed in any orientation This configuration only has to be smooth at one point vs. the traditional interferogram that has to be smooth along a rail ABB Bomem Michelson Interferometer: ABB Bomem Michelson InterferometerABB Bomem Michelson Interferometer: ABB Bomem Michelson Interferometer LaserFast Fourier Transform: Fast Fourier Transform The highest peak intensity is attained when AB=AC The maximum of the highest intensity peak is called the zero path difference (ZPD) point After the interferogram has been created by the instrument, the Fourier transform is applied to it, which then results in a single beam spectrumSingle Beam Spectrum: Single Beam SpectrumSingle Beam Spectrum: Single Beam SpectrumSingle Beam Spectrum: Single Beam SpectrumSingle Beam Spectrum: Single Beam SpectrumTransmission: Transmission The ratio between the sample and the background spectrum Transmittance Spectrum: Transmittance SpectrumChemometrics: Chemometrics Based on the transmission spectrum chemometrics can be applied Chemometrics: The application of statistical and mathematical methods for the design or optimization of chemical experiments and for the efficient extraction of information from chemical data Two types of chemometrics: Qualitative (identification) Quantitative (quantity) Absorbance: Absorbance Beer’s Law: Beer’s Law Says that concentration is directly proportional to absorbance (linearity) Beer’s law equation is A= abC Where A = absorbance a = absorptivity of the molecule b = pathlength that the light travels C = concentration Instrument Resolution: Instrument Resolution The more points per peak the higher the resolution The higher the resolution the more noise, but the better peak separation Common resolution used for an ABB Bomem instrument is 2 cm-1 Ranges between 1 cm-1 to 128 cm-1Why Do We Need a Gas Cell: Why Do We Need a Gas Cell Intensity of a peak is directly related to the # of moles in a sample

absorption Ac = calibrated absorption K = concentration e = noise Using the above equation find K that minimizes e To minimize e we use the CLS method In this situation there are more equations then variablesClassical Least Squares (CLS): Classical Least Squares (CLS) To simplify matters we assume that e = 0 The equation then becomes: As = Ac*K Matrix form: Classical Least Squares (CLS): Classical Least Squares (CLS) In order to solve for K (Ac-1*As = K), Ac needs to be an inverse matrix Therefore: AcT*As = (AcTAc)*K (1x1) = (1x1)*KProblems with Initial CLS Approach: Problems with Initial CLS Approach Baseline becomes unstable throughout the day It can shift, slope, or curve These changes can be compensated for in the calibrated absorption matrix Classical Least Squares (CLS): Classical Least Squares (CLS) Accounting for these baselines changes the equation The eqn. becomes: As = AcK1+ K2+ K3+ K4 The calibrated absorption matrix can be increased to accommodate the number of species being testedWeighted Multi-band CLS: Weighted Multi-band CLS A more complex version of the standard CLS The spectrum is separated into bands Each band is then calculated After all the bands are calculated they are added in a weighted averaged fashion The ones with the highest error and lowest signal are counted for less then the ones with the lowest error and highest signalHardware
