Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) uses a focused laser beam to ablate the sample surface, with the ablated particles carried to an Inductively Coupled Plasma (ICP) source for ionization, followed by Mass spectrometry. This test is offered by Infinita Lab, USA, to clients in the USA and across the world through its vast laboratory network.
Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) uses a focused laser beam to breakdown the sample surface and remove (ablate) fine particulate matter. The particulates are conveyed to an Inductively Coupled Plasma generator (ICP) where the atoms are excited and ionized by high temperature plasma. The ions are then extracted into a coupled mass spectrometer (MS). In the MS, the ions are accelerated and separated based on their mass to charge ratios and their intensities recorded to produce characteristic mass spectra. A recent technical advance involves the use of Femtosecond laser pulses for ablation, to reduce damage to the molecular species being investigated. It also provides an ideal size distribution for transport into ICP-MS for better detection sensitivity.
LA-ICP-MS is used for highly sensitive elemental and isotopic analysis to be performed directly on solid samples. Bulk analysis of solids is done with a typical laser spot size of 100 ~ 350 microns and spot analysis can be done at resolution of a few microns.

ASTM E572 test method covers the analysis of stainless and alloy steels by Wavelength Dispersive X-ray Fluorescence Spectrometry (WDXRF). It provides rapid, multi-element determinations with sufficient accuracy to assure product quality.
The ASTM D2674 test is a standard test method for the analysis of sulfochromate etch solutions used in the surface preparation of aluminum. The ASTM D2674 standard specifies a method for determining the efficacy of an etchant used to prepare the surface of aluminum alloys for subsequent adhesive bonding.
An immunological method for quantization of Hevea Natural Rubber (HNRL) proteins using rabbit anti-HNRL serum. Rabbits immunized with HNRL proteins react to the majority of the proteins present, and their sera have the capability to detect most if not all the proteins in HNRL.
ASTM G65 measures the resistance of metallic materials to abrasion using the dry sand/rubber wheel apparatus. The quality, durability, and toughness of the sample are determined using this test. Metallic materials are ranked in their resistance to scratching abrasion under a controlled environment.
ASTM E2141 test methods provide accelerated aging and monitoring of the performance of time-dependent electrochromic devices (ECD) integrated in insulating glass units (IGU). This test helps to understand the relative serviceability of electrochromic glazings applied on ECD.
ASTM C724 test method is used in analyzing the quality and ease of maintenance of a ceramic decoration on architectural-type glass. This test method is useful in the acknowledgment of technical standards.
