Analytical Laboratory Capabilities and Applications

Analytical laboratory testing capabilities.

Intertek's analytical techniques cover a wide range of expertise and applications, including:

Spectroscopy:

Nuclear magnetic resonance (NMR) is applied in chemical analysis and structure elucidation. We provide several techniques, such as ¹H, ¹³C, ³¹P, ²9Si, and other nuclei, 1D/2D, COSY, HSQC, HMBC, NOESY, TOCSY, DOSY, qNMR on several instruments.

Ultra-violet, visible, and near infrared spectroscopy (UV-Vis-NIR) is applied in chemical analysis, trace analysis, and surface analysis. Intertek offers a large set of sampling techniques such as transmission, remission, and diffuse reflection. We measure fluorescence, phosphorescence, and chemoluminescence.

Fourier transform infrared spectroscopy (FTIR) is applied in structure analysis, surface analysis and microscopy. We provide a large set of sampling techniques for gases, liquids, and solids, such as attenuated total reflection (ATR), diffuse reflection (DRIFT), specular reflection, transmission techniques, photo acoustic spectroscopy (PAS), FTIR microscopy, and FTIR imaging with focal plane array (FPA) detection.

Confocal laser scanning Raman microscopy (CLSRM) is applied in structure analysis, surface analysis and microscopy. We provide several techniques, such as UV-excitation, NIR-excitation, Raman imaging, and Raman mapping.

Mass Spectrometry:

Mass spectrometry (MS) is applied in chemical analysis, trace analysis, and structure elucidation. We provide a large set of ionization techniques, from electron impact (EI), electrospray ionization (ESI), and secondary ion mass spectrometry (SIMS, TOF-SIMS), to matrix assisted Laser desorption ionization (MALDI). Intertek labs perform high resolution mass spectrometry (HR-MS), tandem techniques (MS/MS), and hyphenated techniques, such as liquid chromatography-mass spectrometry (LC-MS/MS) and gas chromatography-mass spectrometry (GC-MS/MS) to characterize complicated mixtures or to identify unknown compounds.

Chromatography:

Chromatographic techniques such as gas chromatography (GC), gel permeation chromatography (GPC), size exclusion chromatography (SEC), high pressure liquid chromatography (HPLC), preparative HPLC, and ultra performance liquid chromatography (UPLC) are applied in chemical analysis, trace analysis, and structure elucidation to separate mixtures. We provide a large set of hyphenated detection techniques such as mass spectrometry (MS) and ultra violet spectroscopy (UV).

Microscopy and Surface Analysis:

Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) are applied for surface analysis and microscopic analysis. Together with energy dispersive X-ray detection (SEM-EDX), electron microscopy is applied for chemical analysis. We provide detecting techniques such as eSEM, GSED, and BSE detection, to investigate a sample's morphology and chemical composition. Conducting and non-conduction samples can be investigated. To achieve the full picture of our samples, SEM-EDX mapping and scanning TEM (STEM-EDX) is applied. Our electron microscopy laboratories are equipped with state of the art sample preparation techniques such as cryo-microtomy and cryo-ultramicrotomy.

Atomic force microscopy (AFM) is applied for the microscopic analysis of surfaces and nano particles. Microscopic information of material properties is gained by different detecting modes such as contact, tapping, force modulation, and spreading resistance.

Optical microscopy is applied for surface and microscopic analysis at a larger scale. Typical techniques include fluorescence, phase contrast, and bright/dark field.

X-ray photoelectron spectroscopy (XPS) or electron spectroscopy for chemical analysis (ESCA) and time-of-flight secondary ion mass spectrometry (TOF-SIMS) are applied for surface analysis. Together with ablation techniques and TOF-SIMS mapping, a 3D picture of the investigated samples is gained.
