Hello everyone, in this video we have to say about the possible interference in the atomic absorption spectroscopy and how these can be solved and what are the possible solutions.
00:11
So the first interference that can occur is the spectral interference, spectral interference, spectral interference.
00:23
So why does spectral interference occurs? spectral interference occurs when, occurs when the analyte and the interfering species absorb at the same wavelength.
00:37
The analyte and interfering substance, interfering, interfering species absorb same wavelength, absorbs same wavelength.
01:02
Now what can be the possible solution to avoid the spectral interference is that we can use a high resolution spectrophotometer or the, or the different technique that does not have this interference, better to have that to, we can use a different wavelength.
01:18
Possible solution can be what? use a higher resolution spectrophotometer, higher resolution spectrophotometer, higher resolution spectrophotometer or we can use different wavelength for the analyte or use different wavelength for the analyte, for the analyte.
02:03
The second kind of interference that can occur is what is the physical interference, physical interference.
02:14
So how can physical interference occur? changes in the sample matrix, change in sample matrix such as viscosity, such as viscosity surface tension, surface tension or a refractive index, refractive index, changes in the sample matrices can cause us physical interference, physical interference.
03:11
Now what are the possible solution to avoid this physical interference? what is the possible solution? so if i talk about the solution, then we can use a method of standard addition or an internal standard to correct these effects...
