Our Instruments
Lambda Research is an evolving, private research facility. We have a unique set of instruments, offering a wide range of spectroscopic, wet chemistry and sample preparation techniques.
FTIR
Fourier Transform Infrared (FTIR) spectroscopy is a powerful analytical technique used in research to identify and quantify chemical compounds. Widely applied across various fields, including chemistry, biology, and materials science, for tasks such as identifying unknown compounds, studying molecular structures, and monitoring chemical reactions. Its non-destructive nature and ability to analyze a range of samples, from solids to gases, make FTIR an invaluable tool in both qualitative and quantitative analysis.
ICP-OES
Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) is a robust analytical technique used to detect and quantify trace elements in various samples. It involves introducing the sample into a high-temperature plasma, which excites the atoms and ions, causing them to emit light at characteristic wavelengths. By measuring the intensity of this emitted light, ICP-OES provides precise and accurate concentration data for multiple elements simultaneously. This method is extensively utilised in fields such as environmental science, geology, and materials engineering for analyzing metals, minerals, and other inorganic substances. Its high sensitivity, rapid analysis, and capability to handle diverse sample types make ICP-OES an essential tool in elemental analysis.
ICP-MS
Inductively Coupled Plasma Mass Spectrometry (ICP-MS) is a highly sensitive analytical technique used to detect and quantify trace elements and isotopes in a variety of samples. The process involves ionizing the sample with an inductively coupled plasma, then analyzing the ions based on their mass-to-charge ratio using a mass spectrometer. ICP-MS is renowned for its exceptional sensitivity, wide dynamic range, and ability to perform multi-element analysis with high precision. This technique is widely employed in environmental testing, biomedicine, geology, and materials science for tasks such as detecting contaminants, tracing isotopic compositions, and analyzing metal concentrations. Its capability to detect elements at parts-per-trillion levels makes ICP-MS an invaluable tool in both research and industry.
Combustion Analysis
Our LECO CHN analyser is a precision instrument used for the accurate determination of carbon, hydrogen and nitrogen content in various materials, including soils, metals, ceramics, and organic substances. Known for its high sensitivity and reliability, the LECO analyser is essential in industries such as soil science, metallurgy, environmental science, and pharmaceuticals, where precise carbon quantification is crucial. Its advanced software and automation capabilities streamline analysis, ensuring consistent and reproducible results, making it a valuable tool for both research and quality control applications.
WDXRF
Wavelength Dispersive X-ray Fluorescence (WDXRF) is an analytical technique used to determine the elemental composition of materials. It involves directing X-rays at a sample, causing the elements within to emit characteristic secondary (fluorescent) X-rays. These emitted X-rays are then dispersed by their wavelengths using a crystal spectrometer, allowing for precise identification and quantification of the elements present. WDXRF is known for its high resolution, accuracy, and ability to analyze a wide range of elements in various sample types, making it a valuable tool in fields such as geology, metallurgy, environmental science, and material quality control.
XRD
X-ray Diffraction (XRD) is a powerful analytical technique used to determine the atomic and molecular structure of crystalline materials. By directing X-rays at a sample and measuring the angles and intensities of the diffracted beams, XRD provides detailed information about the crystal structure, phase composition, and other structural properties. This technique is widely used in fields such as materials science, chemistry, geology, and physics to identify unknown compounds, study crystallographic structures, and investigate material properties. XRD is essential for advancing our understanding of material behavior and developing new materials with tailored properties.
LASER ABLATION
Laser ablation is a precise technique used to remove material from a solid sample using a focused laser beam. This method can be coupled with Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) to enhance elemental analysis. In laser ablation, the laser creates a fine aerosol of the sample, which is then transported into the plasma of the ICP-OES or ICP-MS instruments. This coupling allows for direct, localized analysis of solid samples with minimal preparation, providing high spatial resolution and the ability to detect trace elements. The combination of laser ablation with ICP techniques is widely used in fields such as geochemistry, materials science, and environmental studies for detailed compositional analysis.
UV/VIS
UV/Vis spectrophotometry is an analytical technique used to measure the absorbance of ultraviolet and visible light by a sample. By passing light through a sample and detecting the intensity of transmitted or absorbed light at different wavelengths, this technique provides information about the sample's molecular structure and concentration. UV/Vis spectrophotometry is widely used in chemistry, biology, and environmental science for applications such as quantifying nucleic acids and proteins, analyzing chemical reactions, and detecting contaminants. Its simplicity, rapid analysis, and versatility make UV/Vis spectrophotometry an essential tool in both research and industrial laboratories.
pXRF
Portable X-ray fluorescence (PXRF) is a non-destructive analytical technique used to determine the elemental composition of materials. By utilizing a handheld X-ray device, PXRF enables in-field, real-time analysis without the need for sample preparation. The device emits X-rays that interact with the atoms in the sample, causing the emission of secondary (or fluorescent) X-rays that are characteristic of the specific elements present. This technology is widely employed in various fields, including archaeology for artifact analysis, environmental science for soil and sediment testing, and art conservation for studying pigments and materials in artworks. PXRF's portability, ease of use, and rapid results make it an invaluable tool for on-site investigations where traditional laboratory analysis is impractical.
GC
Gas chromatography (GC) is a powerful analytical technique used to separate and analyze compounds that can be vaporized without decomposition. By passing a sample through a chromatographic column with the aid of a carrier gas, GC enables the resolution of complex mixtures into individual components based on their volatility and interaction with the column's stationary phase. Coupling GC with inductively coupled plasma mass spectrometry (ICP-MS) or inductively coupled plasma optical emission spectrometry (ICP-OES) combines the separation power of GC with the sensitive, multi-element detection capabilities of ICP techniques. GC-ICP-MS allows for the detection of trace elements with high sensitivity and specificity, making it ideal for applications such as environmental monitoring, food safety, and bioanalysis. GC-ICP-OES, on the other hand, provides robust quantification of multiple elements simultaneously, which is particularly advantageous for industrial and geochemical applications. The integration of these techniques enhances analytical precision and accuracy, offering comprehensive insights into the elemental composition and chemical structures of complex samples.
