Light shield cover
Tip
Try to use the provided sampling sheet B
for a minute sample.
Using this sheet, the entire flat sensor can
be covered with only 50 L to 100 L
sample.
 Note that a reaction between a
sample and the sampling sheet B
may affect the measured value.
 Handle the sampling sheet B with tweezers to minimize possible
contamination.
 Make sure to close the light shield cover during measurement to
minimize possible sample evaporation.
