1: Introduction

About Raster Orbital Scanning (ROS)

The Ocean Optics IDRaman mini uses ROS to rapidly scan a tightly focused beam in an orbital pattern,
allowing lower average power to produce high-integrity data from a larger area of the sample without
sample ignition or dam age.

A tightly focused beam may result in no is y sign al s
or missing the Ra man acti v e tar g et co mpl e te l y,
leading to false negative readings from unidentified
samples.

Increasin g the spot size of the laser dilutes the
valuable inf or mat ion ab ou t th e mat eri al, le ading to
inconclusive matches or false identification of
samples.

ROS increas es the ef fe c ti ve size o f a tight ly
focused beam. In f o rm at ion is ob t ain ed with
complete integrity while sampling the large area
needed for complex mixtures or irregularly shaped
samples, lead in g to c onfident identification.

Acquiring a Reference and Spectrum

Spectra can be acquired several different ways depending on your application or on the sample’s
composition.

Button Function

Acquire

Reference

000-40000-010-02-201311 15

Acquires a spectrum for the integration time. The laser turns on for a period of time
determined by the integration time. Some delays exist to allow for the laser
stabilization; however, the exposure time is precisely set by the integration time
selected.

Acquires a dark reference for the set integration time. Normally the shutter closes
during this period and the reference spectrum is subtracted from the acquisition.
This removes any environmental background and it eliminates any fixed pattern
noise due to the CCD detector.

The slide switch at the top: Use Reference determines if a reference is used. Use

Reference (Yes) causes the reference to be subtracted; this is the default. Select
Use Reference (No) if you do not want the reference subtracted.

NOTE: It is essential to have the reference acquired for the same integration time as

the acquisition. If there is a mismatch, a new reference will be automatically
acquired at the new acquisition time.

2: Set-up and Operation

Acquiring an Average

Averaging is used when your sample has a high background. Often samples will produce some or even
large amount s of flu or e sc en ce. The qualit y of a spect ru m is d ete r min ed by the si gn al -to-noise. The noise
is determined by “shot noise” which is equal to the square root of signal. This means that samples with
large backgrounds will inherently have poor signal-to-noise ratios. Increasing the integration time will
improve the signal-to-noise ratio, but with high background samples this may be impossible due to the
detector’s li mi ted d yna mi c range.

Averaging allows one to take multiple short acquisitions and average them to improve signal to noise.
Until the detector becomes dark noise lim ited the signal to noise ratio will improve by the square root of
the number of averages.

Button Function

Average

Peak Clean

Peak Clean is a beta correction algo r ithm to produce spectra that are baselined corr ected with powerful
de-trending algorithms. This method is not appropriate for every sample, but when spectral backgrounds
are a probl em it can provide backgrou nd free spectra. Peak Clean can be par ticularly useful for library
matching.

Acquires multiple spectra which will be averaged. When the average button is
selected the # of averages control box appears. Select the number of averages and
begin the averages by depressing the average button again.

NOTE: Average will acquire a full set of averaged references before it begins

acquiring spectra.

Wavenumbers

Dynamic Raman Scattering (DRS)

DRS is a spectroscopic technique developed to enhance spectra produced by free floating particles in
solution. The feature is available both on the system’s firmware and in IDRaman Software.

DRS measures the extra noi se created when particles move in and out of the laser beam used to create the
spectrum. This technique was developed by Scott and Carron
material surrounding the moving particles and the container material.

The principle of DRS is that the solvent matrix surrounding small free floating particles is constant and
the container material is also constant. However, the spectrum produced by a low concentration of
particles will exhibit large fluctuations due to their movement in and out of the laser beam.

Button Function

DRS

When this button is pressed the software pops up a control for the number of spectra
to acquire. When the DRS button is released the IDRaman mini acquires and
displays the number of spectra chosen. DRS will produce optimal results with short
integration times and statistically most significant with a relatively large number of
acquisitions.

When the acquisitions are completed the DRS spectrum will be displayed.

IDRaman mini i n an ASCII format which can be opened by any spreadsheet software.

• LibraryTemp – Contains the same time and date stamped files saved using the Save

function

on the IDRa man mini but in the .lib format. These files can be renamed

and transf erred into the library fold er.

• Library – Contains the Library (.lib) files that are used in the library search. The name of

these files w il l be disp l a yed on the IDR a man mi ni sc re en wh en th er e is a mat ch .

4. If you created libr a r y files u sin g the IDRaman Software you can copy and paste those files into
the Library folder to add more compounds to the library.

5. If you saved a spectrum of a compound using the Save function on the IDRaman mini, follow
these procedures to add the file to th e lib ra r y. A saved sp e ctr u m of toluene is used for an
example.

Building a Secure Library

► Procedure

1. The first tim e you build a lib rary your folder, c:\users\public\snrisecurelibrary\ should contain
the file sri_libcrypt_mono_v3.

2. Load your librar y folder o f spe ct ra acq ui red with the IDRaman Software as .lib files into the
snrisecurelibrary folder. Your folder should now appear as follows:

3. Run the IDRaman Software and select the Secure Library button. This will invoke the Secure
Library dialog.

2: Set-up and Operation

4. After you have entered your library folder name and an allowed output file name, the dialog will
ask for your security key. T his is the 32 characters that will go into the keyfile.txt. A counter is
provided to the right of the Secure Libr ar y dia log. Wh en you ha ve en ter ed your 32-bit security
key, the routine will au to m at ica lly create your encr ypted lib ra r y.

5. Once you have successfully created your encrypted library (compound.usr), it will appear in the
snrisecurelibrary folder. It can now be transferred t o the IDRaman m ini using the USB drive tool.
It should go in the Library\ folder.
