Quantitative Chemical Analysis or quantitative chemistry, EUROLAB to accurately determine the concentration, amount or percentage of one or more elements in a test sample. Trace metal analysis is presented using EUROLAB's highly sensitive instrumentation.
Quantitative analysis, together with the qualitative analysis technique, provides information about the type and quantity of each element in a sample for full element analysis.
ELEMENT ANALYSIS EXPERTISE
TURCLAB in Turkey. Has the ability to provide quantitative or semi-quantitative results in some cases, liquid and solid samples for elemental analysis by using various techniques. The best method of analysis often depends on the type of sample, the amount of material available for analysis, the desired result, and cost constraints.
Many of these methods provide trace metal analysis and can detect parts-per-billion concentrations and even part-per-trillion ranges using some of the latest spectroscopy equipment in the lab. Almost all of these quantitative analysis services, with the exception of the PMI Test, are considered destructive because a small sample must be removed from the material to perform the test.

EUROLAB CAPABILITIES
QUANTITATIVE ANALYSIS PROCESSES ATOMIC EMISSION SPECTROSCOPY Atomic Emission Spectroscopy determines major, minor and trace elements and is particularly useful for low atomic elements such as boron, aluminum, calcium, magnesium and phosphorus. Elemental analysis with AES is the process of energizing atoms in a test sample to create emission lines or wavelength bands from the emitted light. Atoms create their own unique patterns, and the density of the emission lines increases in proportion to the number of atoms that produce the lines. The analysis requires the emission lines to be compared to standards known from the sample to identify the element and calculate the amount of element. The sample is prepared by grinding it to obtain a smooth, clean, flat area. The atoms in the sample are energized using a rapid series of high energy sparks in an argon-filled space between an electrode (cathode) and the surface of the sample. When excited atoms in the plasma relax (excitation) to a lower energy state, they emit light at characteristic wavelengths for each element. ICP-AES ANALYSIS ICP-AES is another technique for analyzing the concentration of metallic elements in test samples using energetic atoms. ICP-AES analysis can determine major major element concentrations with detection limits at parts per billion level for some elements. ICP-AES analysis can be performed on solid and liquid samples, but a solid sample must be converted to liquid form before testing. Solid samples are dissolved in an element (typically acid) to obtain a solution for elemental analysis. The sample solution is introduced into the ICP as a fine aerosol of droplets produced by a nebulizer. Plasma consists of argon gas operated at atmospheric pressure and inductively coupled to a radio frequency (RF) electromagnetic field. The spectrometer detects the atomic emissions produced. Computer software is used to control and monitor instrument functions and to process, store and output analysis results. ICP-MS ANALYSIS ICP-MS analysis provides highly accurate elemental analysis and can often perform multi-element tracking analysis at the part-per-trillion level. ICP-MS spectrometers can perform both qualitative analysis and quantitative analysis and offer the following features:
As with the ICP-AES analysis, liquid samples are placed in the ICP via a nebulizer that aspirates the sample with high velocity argon and creates a fine mist. The aerosol then passes into a spray chamber where larger droplets are removed. Droplets small enough to be vaporized in the plasma torch pass into the torch body where the aerosol is mixed with more argon gas. A coupling coil is used to transmit radio frequency to heated argon gas, producing an argon plasma embedded in the torch. The hot plasma removes the remaining solvent and causes sample atomization followed by ionization. COMBUSTION ANALYSIS Carbon and sulfur are easily oxidized and release oxide gas as metal. High temperature combustion is used to obtain the content of these elements in a material. The combination of high temperature mixed oxygen causes the sample to burn in a furnace. The gases are passed through a series of traps, absorbers and converters to remove the interfering elements and ensure that the gases have the proper structure for detection. Infrared detection is used to determine the carbon or sulfur concentration. Infrared detector is used on the basis that various gases can absorb energy within a certain wavelength of the infrared spectrum. The amount of energy absorbed is related to the amount of carbon or sulfur in the test sample. INERT GAS FUSION Inert gas fusion is used to determine the content of hydrogen, nitrogen and oxygen gases in ferrous and non-ferrous materials. Gases are formed as a result of melting processes and subsequent hot and cold processing methods. Controlling the gas content to low levels minimizes adverse effects on mechanical properties such as strength and ductility. Inert gas method separates the gases from the material by reversing the bond between them. The gas to be analyzed flows into an infrared or a thermoconductivity detection system for quantitative analysis. ENERGY DISTRIBUTOR X-RAY SPECTROSCOPY (EDS) Energy Dispersive X-ray Spectroscopy analyzes the chemical characterization of a sample by separating the characteristic X-rays of different elements into an energy spectrum. This is represented as a histogram of the X-ray energy received by the detector, with individual peaks that are proportional to the amount of a particular element in the analyzed sample. The EDS system software analyzes the energy spectrum to identify elements in the sample and determine the abundance of specific elements for semi-quantitative information. EDS systems are typically integrated into a device such as SEM with high resolution and magnification. This system can be used to find the chemical composition of materials down to a spot size of a few microns and to create element composition maps over a larger scan area. EDS is also useful for identifying coatings and foreign matter on the surface of a wide variety of materials. PMI TEST Portable X-ray fluorescence spectroscopy is a Positive Material Identification or PMI Test technique that can be used for direct analysis of solid metal samples, thin metal films and a variety of other materials. This method does not damage the sample and portable equipment can be used for analysis in the field. This type of semi-quantitative chemical analysis uses X-ray rays to irradiate the sample. When all the energy of the primary X-ray is absorbed by an electron in the innermost electron shell of an atom, excitation and ejection of the absorbing electron occurs. Electron spaces are filled with electrons in higher energy states, and X-rays are emitted to balance the energy difference between electron states. X-ray energy is characteristic of the element with which it is emitted and is directed to an X-ray detector in the XRF unit where it is recorded. The intensity of the X-ray energy is compared with the values of known standards to provide information about the unknown sample. FOURIER TRANSFORMATION INFRARED SPECTROSCOPY (FTIR) FTIR is used to analyze many organic materials, including plastics and other polymers. The technique produces a spectrum that provides inborn details about the bonding properties between atoms or characteristic functional groups in a molecule. AGE CHEMISTRY Before the widespread availability of analytical instruments, quantitative chemical analysis was routinely performed by wet chemistry methods. This type of elemental analysis requires thawing the sample and performing a specific chemical reaction with a standardized reagent for each element of interest.
