What is ICP-OES instrument?

ICP-OES equipment ICP-OES (Inductively coupled plasma – optical emission spectrometry) is a technique in which the composition of elements in (mostly water-dissolved) samples can be determined using plasma and a spectrometer.

What is LA-ICP-MS used for?

LA-ICP-MS (Laser Ablation Inductively Coupled Plasma Mass Spectrometry) is a powerful analytical technology that enables highly sensitive elemental and isotopic analysis to be performed directly on solid samples.

What does ICP measure?

Intracranial pressure (ICP) monitoring is a diagnostic test that helps your doctors determine if high or low cerebrospinal fluid (CSF) pressure is causing your symptoms. The test measures the pressure in your head directly using a small pressure-sensitive probe that is inserted through the skull.

Is LA-ICP-MS destructive?

LA-ICP-MS is a minimally-destructive method for trace elemental analysis of solids. A solid sample is ablated with a laser, which produces particulates.

What can ICP-OES detect?

Metals such as Fe, Pb, and Cu are measured by ICP-OES in the same way as nonmetals like Cl, Br, I, S, and P. The main steps in ICP metal analysis are: The elemental metals to be measured in the sample to be are selected. For example, iron (Fe), lead (Pb) and copper (Cu).

What is the difference between ICP MS and ICP-OES?

ICP-OES is mainly used for samples with high total dissolved solids (TDS) or suspended solids and is, therefore, more robust for analyzing ground water, wastewater, soil, and solid waste. ICP-MS, on the other hand, is especially useful for analyzing samples with low regulatory limits.

How does an ICP-OES work?

The ICP-OES principle relies on those excited atoms releasing light at specific wavelengths as they transition to a lower energy level.

1. As an electron returns from a higher energy level to a lower energy level, usually the ground state, it emits light of a very specific wavelength.
2. Energy level diagram for lead (Pb).

What elements can ICP-OES detect?

Detection limits. Elements including As, P, Rb, Se, and S have detection limits of a few part per billion (ppb, ng/mL). Detection limits for F, Cl, and Br are typically in the hundreds of ppb (ng/mL) or more unless the spectrometer can measure lines below about 150 nm.

How does LA-ICP-MS work?

LA-ICP-MS uses a powerful nanosecond-pulsed laser beam to remove material from the surface of a sample. The sample material is subsequently ionized in an inductively coupled plasma, and its atomic species are transported as ions, separated and analyzed based on their mass-to-charge ratio over time.

How much does a LA-ICP-MS cost?

The other major consumable in ICP-MS is the detector, which has a lifetime of approximately 1 year, and costs about $1200–1800. When all these are added together with the torch, the sample introduction components, and the vacuum pump consumables, investing in ICP-MS supplies represents an annual cost of $9,000-11,000.

How does an OES work?

OES analysis uses a sparking process, which involves applying an electrical charge to the sample, vaporizing a small amount of material. Once this spark occurs, a discharge plasma with a distinct chemical signature is created, allowing our experts to determine the elemental breakdown of the sample.

What are the different types of ICP-OES instruments?

There are two main types of ICP-OES instrument: sequential ICP-OES spectrometers measure each element in turn by “scanning” from one element to the next, whereas simultaneous instruments measure all the programmed elements at one time.

How is the ICP-OES used in atomic spectroscopy?

Instrument description: The instrument Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) is used in atomic spectroscopy, and during analysis the sample is decomposed by intense heat into a cloud of hot gases containing free atoms and ions of the element(s) of interest.

How is thermal excitation used in ICP-OES analysis?

During ICP-OES analysis the intensity of the light emitted at specific wavelengths is measures and used to determine the concentration of the element(s) of interest. In ICP-OES analysis the thermal excitation can populate a large number of different energy levels for several different elements at the same time.
