Inductively Coupled Plasma (ICP).

Front

What is birefringence?

Back

The numerical difference in refractive indices.

Front

What is the main purpose of Atomic Absorption Spectroscopy (AAS)?

Back

To determine the concentration of elements in a sample by measuring the absorption of light.

Front

What type of light source is commonly used in AAS?

Back

Hollow cathode lamp.

Front

What is the role of the plasma in Inductively Coupled Plasma (ICP) techniques?

Back

To atomize and excite the sample for analysis.

Front

What is the difference between qualitative and quantitative analysis in elemental analysis?

Back

Qualitative analysis identifies the elements present, while quantitative analysis measures the amount of each element.

Front

What is the principle behind Mass Spectrometry (MS)?

Back

It measures the mass-to-charge ratio of ions to identify and quantify molecules.
