ROS Sampling Advantage
Convenient Sampling
High Resolution and Laser Line Options
The IDRaman reader features three convenient ways to sample. Point the source
knob down and measure the area just below the IDRaman reader. Adjust the
focus for maximum sensitivity. This configuration is ideal for process Raman
measurements or reading SERS substrates.
The adjustable focus sample chamber also allows you to sample vials two
ways. The adjustable focus sample holder maintains laser safety while allowing
you to measure from the bottom of the vial to get the best results from the
smallest amount of sample. Traditional sampling from the side of a cuvette
or vial is also available.
The IDRaman reader is available in a variety of different configurations with the
choice of 532, 638, 785 or 808 nm laser excitation each available with two
resolution options. The 8 cm
-1
version covers the Raman spectrum from 200 to
3,200 cm
-1
for samples requiring a wide measurement range like aliphatic
hydrocarbons. The high-resolution 4 cm
-1
version covers from 200 to 2,000 cm
-1
;
use this configuration to get the most detail near the laser line.

Raman is an average power technique and ROS keeps the laser power high
without damaging samples. ROS samples many Raman-active compounds,
making it ideal for Surface Enhanced Raman Spectroscopy (SERS) substrates.
A tightly focused beam may give
noisy signals or miss the Raman
active target completely. Simply
increasing the spot size of the laser
dilutes the valuable information
about the material. This leads to
low-resolution data and inconclu-
sive library matches. ROS sampling
provides the best possible Raman
data by scanning a tightly focused
beam over a large sample area.
