Why we are using only KBr in IR spectrometer why not KCl..

Answer / ramkrishna thakare

KBr shows Absorbance in 2.4 -16 MICROMETER of IR REGION.
While other compound shows Transmittance in 2.4 -16
MICROMETER of IR REGION. & hence resolution is not achieved .

& for the purpose of resolution & background correction KBr
is the best option.

Why we are using only KBr in IR spectrometer why not KCl..

Answer / ramalaxmi ch

KBR can not absorbance in IR region. and it is a primary standard.
KBR does not catch the moisture easy better than KCL
KBR STABLE also

Why we are using only KBr in IR spectrometer why not KCl..

Answer / jayalakshmi

KBr is optically transparent over the range of wavelengths
in the wavelength range of IR analysis. This means KBr does
not have any absorbance in IR region.

Answer / manoj patel

KBr gives better resolution than KCL...
KBr could not have any absorbance in IR range
Kbr coild not interference with other compounds in IR Range.

Is This Answer Correct ?    4 Yes 1 No

Why we are using only KBr in IR spectrometer why not KCl..

Answer / naresh

Kbr is ir inactive

Is This Answer Correct ?    2 Yes 0 No

Why we are using only KBr in IR spectrometer why not KCl..

Answer / paresh jobanputtra

Actuly alkli halide are used for this perpose..because they
are inert and could not have any absorbance in IR range..so
we can use kcl instead of kBr...

Is This Answer Correct ?    11 Yes 11 No

Why we are using only KBr in IR spectrometer why not KCl..

Answer / parag parekh

we can use both kbr & kcl because they could not have any
absorbance in the ir region.

mostly for the compound having cloride group the kcl is
better option than kbr.
