Why is Erbium perchlorate is used in calibration of HPLC?
Erbium has a strong absorption in uv and visible range, It is used in HPlc calibration for the wavelength accuracy verification of the PDA detector.
Can C18 column for HPLC be used with UV and visible spectra detector and Acetonitril as mobile phase?
Of course.... there isn´t problem....
Is ultraviolet radiation is visible or invisible?
It's detected by means of a camera that is sensitive to infra-red light. Visible light forms only a tiny portion of the electromagnetic spectrum.
Which has the lowest frequency uv- b uv- a uv- c?
UV-A
Why are UV rays invisible?
UV rays are part of electromagnetic spectrum just like light. Some rays can be detected by the eye and some cant. The sunlight we see is the visible part of this spectrum that is why it is called visible light. Initially only light would reach the earth but now because of ozone depletion even UV rays reach the earth. So basically they are invisible because they are not part of visible light.
How you can analyze pregabalin on HPLC with UV detector?
We can quantitatively analyse pregabalin on hplc with uv detector, wavelength will be 210 n.m. and mobile phase will be 5 % acetonitrile. standard & sample solution preparation should be in mobile phase.
What is Difference Between HPLC UV detector Spectrophotometer uv detector?
hi, could any one answer what is the difference between hplc uv detector and spectrophotometer uv detector ? my id is debendra_mallick2002@yahoomail.com
Why acetone used in hplc calibration?
UV cut off of acetone is 330 nm and it is easyly available,non expensive. you can use any other solvent which has UV cut off above 250.
What is difference between an HPLC UV detector and a fluorescence detector?
flourescence is more sensetive than UV detection
Why is Erbium perchlorate is used in calibration of HPLC?
Erbium has a strong absorption in uv and visible range, It is used in HPlc calibration for the wavelength accuracy verification of the PDA detector.
How can you detect U.V. from sun?
UV from sun could be detected using UV sensors. The technology has been that advanced.
Can C18 column for HPLC be used with UV and visible spectra detector and Acetonitril as mobile phase?
Of course.... there isn´t problem....
How Lambda max determined for quetiapine fumarate?
by injecting the sample in to a HPLC system having PDA detector or Scan the Quetiapine Fumarate sample solution in UV range.
Is ultraviolet radiation is visible or invisible?
It's detected by means of a camera that is sensitive to infra-red light. Visible light forms only a tiny portion of the electromagnetic spectrum.
What difference between pda and uv detector in hplc?
PDA - Photo diode array UV- Ultra violet with use of PDA detector, we can measure the area or height of particular peak at different wavelengths ranging from 200 to 800 nm by injecting the solution at once. Where as in uv detector we can measure the area or height of the peak only at two different wavelengths. But that wavelengths also to be selected before injecting the solution.
How do you see ultraviolet waves?
Ultraviolet light is not visible. Many ultraviolet lamps also emit some visible light along with the ultraviolet, typically visible violet. Also, ultraviolet light is an ionizing radiation, and will cause some flourescent materials to emit various visible wavelengths of light.
What type of invisible radiation from space can be detected from earth?
Long wave radio, short wave radio, microwave radio, heat, far infrared, near infrared, ultraviolet UV-A, ultraviolet UV-B, high energy X-rays, high energy gamma rays.
