Samples may be in liquid, solid, or gaseous form. MCL has a significant collection of sampling accessories. See below. Additional sample requirements vary widely depending upon the specific technique employed for analysis. FTIR Instrumentation Bruker Vertex V80v, V80 and V70 The MCL has three high performance research grade FT-IR spectrometers. The V80 and V70 are equipped with a wide range of sampling accessories. Through the use of interchangeable optical components MCL has the ability to acquire data over the near-IR (12, 000-4, 000 cm -1), mid-IR (4, 000-400 cm -1), and far-IR (680-30 cm -1) regions. Additionally, the V80 is a step-scan capable instrument for high temporal resolution spectrometry. The evacuable optics bench of the V80v vacuum FTIR spectrometer allow acquisition of data in the mid-IR and far-IR regions without the interference of atmospheric water and carbon dioxide. Bruker Hyperion 3000 Microscope The Hyperion 3000 FT-IR microscope enables the acquisition of mid-IR and near-IR spectra from very small (>10 µm) samples with diffraction limited spatial resolution.

This is called the fingerprint region. Question: What is the functional group region IR? Answer: The functional group region runs from 4000 cm-1 to 1450 cm-1, and the fingerprint region from 1450 cm-1 to 500 cm-1.... The functional group region contains relatively few peaks. These are typically associated with the stretching vibrations of functional groups. Popular posts from this blog To determine loss on drying (LOD) Definition: Loss on drying compares the weight of product sample before and after drying. The result is the percentage of moisture in a product. % Moisture = (Begging weight-Ending weight) X 100 ----------------------------------------------- Begging weight Loss on drying determine by two method which is given below: Method (1): Weigh accurately a dry empty glass Petri dish. Put the sample (about 0. 5 to 5 gm as par requirement, Its mean if sample having less wet take 5 g weight. If sample having more wet than take 0. 5 g weight) in dish and weigh. Note down the reading.

The Benefits: The biggest advantage of method validation is that it builds a degree of confidence, not only for the developer but also to the user. Although the validation exercise may appears costly and time consuming. It is results in expens Handling of Laboratory Incidents What is Incident: Any unplanned or uncontrolled event in the form of non-compliance to the designed systems or procedures at any stage of testing, and storage of drug product due to system failure or equipment breakdown or manual error. A laboratory Incident is an event in the laboratory that occurs for two primary reasons either due to analyst error or instrument error. Few example of laboratory incidents: Use of expired reagents/working standard/reference standard System suitability fail. Improper peak shape or peak split. Relative retention time shift. Communication failure between software and hardware during analysis. Power failure during analysis. Temperature of laboratory found out of acceptance criteria. Out of calibration instrument used for analysis.
A review of FTIR and Raman spectroscopy methods and discussion of the range of materials analysis applications FTIR is able to capture rich absorbance and emission spectral data from a wide array of liquids, gases, and solids making it well-suited for manufacturing, quality control, and failure analysis, among other uses. Raman, when coupled with microscopy, is able to discern fine surface structure for chemical analysis and 3-D depth profiling of optically transparent substances, using non-destructive techniques. Both platforms are also used in polymer analysis and are important in plastics identification and characterization. Hence, they are important tools for detection of microplastics in the environment as well as plastics accumulation in biological specimens and consumer goods such as drinking water. Although the two techniques can be complementary, they each are based on distinct physical processes and measurements. Here we take a brief moment to dissect FTIR versus Raman spectroscopy.
The IR spectra of this new resist films on silicon substrates were measured with a Shimadzu FTIR-4000 Fourier transform spectrometer. The UV spectra of 4, 4 -diazidodiphenyl methane in a quartz cell and the films of poly(styrene -co- maleic acid half ester) and the new resist on quartz substrates were measured with a Shimadzu UV-265FS double-beam spectrometer. [Pg. 270] Measurements. High performance liquid chromatography (HPLC) measurements were performed by using C18 column with a Shimadzu LC-9A and SPD-6A (UV spectrophotometric detector).

FTIR Gas Analyzers Gasmet manufactures portable FTIR gas analyzers and stationary FTIR emissions monitoring systems. An FTIR analyzer works by simultaneously scanning the entire infrared spectrum. Then, the software calculates the concentrations of each gas in the sample based on the characteristic absorption. All the gases in the sample can be measured simultaneously because the entire infrared spectrum is scanned at once. This allows for very quick multicomponent measurements and for compensation for any cross-interference. As all gases are measured by scanning the same infrared spectrum, adding new compounds can be done easily in the software without requiring any changes to the hardware. The recorded spectra are also unaltered by the analysis performed on them and can therefore always be re-analyzed. This allows for traceable data and facilitates for instance retrospectively checking the measurements for new gases. All this makes FTIR the ideal solution for a variety of applications where multiple gases need to be measured quickly, accurately and reliably.
