Answer / prasad
Because Only holmium can give sharp peaks in both UV and
Vis range, Sharp peak is very rare in UV/Vis spectroscopy.
It is very stable and doesn't absorb light at lower
wavelength.

IN THE PARAMETER OF CONTROL OF WAVELENTH
ONLY HOLMIUM OXIDE CAN GIVE ALL PEAKS
AT PERTICULAR WAVELENTH IN BETWN 200 NM TO 600 NM.

Answer / deepak
holmium oxide in perchloric acid solution gives very sharp
peaks in the range 200 nm to 900 nm. and hence is used as a
calibration standard.

Answer / ragni vora
this is because holmium oxide and perchloric acid does not absorb uv/vis i.e. it is transparent to uv/vis region hence it can also be used as an background

Please give idea about method development for cleaning method and how maco level establish
what parameters we will consider while developing a HPLC method and how we confirm our HPLC method is valid?
How we develop a method by HPLC for unknown compound,if we got three peaks with same response then how we can find out which one is our desired compound's peak without taking help of LC MS.
