Z Dimension of Spectrophotometer Cuvettes
What does
Z height mean?
Z
Height/Dimension is defined as the distance from the bottom of the cell
compartment in your instrument to the center of the light beam.
Why Z
Height/Dimension is Important?
Each instrument
manufacturer makes engineering decisions for the design of their instrument to
assure that it performs optimally. The height, width, focus and placement of
the light beam in any instrument is based on the engineering decisions to
assure that the instrument performs to their published specifications. It is
important to you, as the instrument user, only when you are attempting to use a
small sample volume. You must assure that your smaller volume is placed in the
centre of the light beam and that any light which does not pass through your
sample is blocked (or masked) by blocked (or masked) by black material. If the
cell is not properly masked then the sensitivity will be eroded.
How can I
determine the Z Height of my instrument?
You can test for the
Z dimension of your instrument very easily. Simply follow these steps:
1) Cut a piece of dense paper 12mm wide and 100mm long.
2) Make a hole in the centre of the paper about 3mm in diameter (just push a
ballpoint pen through the paper) 8.5mm from the bottom of one end and 15mm from
the bottom of the other.
3) Turn on your spectrophotometer in %T mode and set to any reasonable
wavelength.
4) Place the piece of paper with the hole in the end into the cell holder as if
it were a cell. Whichever end (either 8.5mm or 15mm) transmits light will tell
you the Z dimension of your instrument.
5) If neither works then make up another piece of paper with holes placed at
different dimensions and determine which works best.
