What are the application of ICP-MS?

What are the application of ICP-MS?

(LA-ICP-MS) has already successfully been applied to applications in forensics, metals, glasses, soils, car paints, bones and teeth, printing inks, trace elemental, fingerprint, and Paper. Among these, forensic glass analysis stands out as an application for which this technique has great utility to provide highly.

Where is ICP used?

ICP-MS can be used to measure the individual isotopes of each element; this capability brings value to laboratories interested in one specific isotope of an element or in the ratio between two isotopes of an element.

What is the principle of ICP-MS?

Principle. Like for the ICP-OES, the sample solution is introduced into the device by means of a peristaltic pump. There it becomes nebulized in a spray chamber. The resulting aerosol is injected into an argon-plasma that has a temperature of 6000-8000 K.

What types of samples can be analyzed by ICP-MS?

ICP metal analysis can be performed on solid and liquid samples, but a solid sample must be converted to liquid form before testing by dissolving the sample in a solvent (typically acid) to produce a solution. The sample solution is introduced into the ICP as a fine aerosol of droplets.

Why has ICP-MS become an important and widely used analytical method?

ICP-MS has become an important tool for elemental analysis because of its high sensitivity, its high degree of selectivity, and its good precision for determining many elements in the periodic table.

How is ICP-MS used in forensics?

LA-ICP-MS is an elemental and isotopic microanalytical technique that is increasingly used for routine analysis in forensic laboratories around the world due to its great discriminating power between samples and its capacity for analyzing solid evidence of small size.

What are the components used in ICP?

Structure of ICP-MS As shown in Figure 1, ICP-MS consists of an ion source (ICP), a sampling interface, ion lens, a mass spectrophotometer and a detector. The ion source, ICP is an ideal ionization source for mass spectrometry, and can ionize over 90% of many elements.

What function does the ICP torch have in ICP-MS?

In ICP mass spectrometry (ICP-MS), an inductively coupled argon plasma torch is used to atomize and ionize a sample, which is usually introduced as an aerosol or by means of laser ablation.

What is ICP forensic science?

What is alternative light photography?

We look at using ultraviolet light to enhance bruises and bite marks, and search for trace evidence. Infrared photography is used to enhance difficult to see blood on dark and patterned clothing, and tattoos post-mortem difficult to see due to decomposition, lividity and burning.

How is the HPLC system connected to the ICP-MS?

The HPLC system was connected to the ICP-MS using the Agilent LC connection kit. An anion exchange column (4.6 mm internal diameter × 30 mm polyhydroxymethacrylate base resin) was used for separation.

What is ICP-MS and why is it important?

ICP-MS in semiconductor manufacturing When ICP-MS was introduced in the 1980s, it was of great interest to semiconductor manufacturers and chemical suppliers due to its high sensitivity, low detection limits, and multi-element capability.

Why use ICP-MS for semiconductor measurement?

Use of ICP-MS for semiconductor applications increased rapidly in the 1990s, with the development of “cool plasma” on the HP 4500 instrument. Cool plasma allowed Na, K, Ca, and Fe to be determined at trace levels by ICP-MS, so semiconductor manufacturers and chemical suppliers no longer needed graphite furnace AAS to measure these elements.

How is the Agilent 7500c ICP-MS used in HPLC?

An Agilent 7500c ICP-MS was fitted with a microconcentric nebulizer and operated in organic mode. HPLC-ESI-MS was performed using an Agilent 1100 Series LC/MSD in positive ion scan mode. Instrument operating conditions are shown in Table 1. Results Analysis by reversed-phase (RP)-HPLC using ICP-MS as a
