1. Introduction to the Serstech 100 Indicator

Raman spectroscopy is a spectroscopy technique which can be used for rapid identifi-

cations of chemicals. The Raman effect occurs when a light (e.g. from a laser) interacts

with the sample molecules. Light scattered from the molecules gives rise to a spectrum that

typically consists of a series sharp lines and constitutes molecules fingerprint.

The Serstech 100 Indicator is a hand-held Raman spectrometer which can be used

without formal training in spectroscopy to obtain chemical identity of substances as well as

verify the quality of known substances in order to be able to make immediate action deci-

sions in the field. It also includes a function to screen for regulated substances. The Indica-

tor is a standalone instrument that operates without need for other components. However,

the instrument relies on access to libraries stored in the instrument and/ or ability to create

and update these libraries externally. Basic computer knowledge is required for adminis-

trating the libraries and the users. Laser training is needed for all users since the instrument

includes class 3B invisible laser.

This manual describes the basic functions of the Indicator as well as the connection to

the software ChemDash ONE. Functions may be different depending on the hardware and/

or software version in the device. The manual covers Indicators with embedded software

functionality version 5.3.0 or later.

The software version is shown in the “About” window. The serial number of the instru-

ment is printed on the back of the instrument (S/N) and is also shown in the “About”window

for software.

Please NOTE that you can access ChemDash ONE only if your instrument is running

software version 4.0.1 or later. If your instrument is running an older version, please

upgrade the firmware first by following the instructions in the Firmware Upgrade

Guide on serstech.com

1.9 Invisible laser Safety Considerations

This operation manual includes information and warnings which must be observed

by the user. It contains information NOTEs as well as information of importance to safety

of personnel and property. The important symbols are:

This is a Class 3B laser product and complies with “Classified

according to standard EN 60825-1:2014”.

Class 3B requirements:

A class 3B device shall have a warning signal, audible or visi-

ble when the invisible laser is active. A red LED in a yellow

warning label placed adjacent to the display solves this re-

quirement. According to the standard, there shall be a yellow

label with a black border, the recommended wording is:

WARNING –INVISIBLE LASER RADIATION

AVOID EXPOSURE TO BEAM

CLASS 3B LASER PRODUCT

The backside label on the Serstech 100 Indicator solves this

requirement. Also, the frontside label has the word WARNING

according to standard requirements. Another requirement is

that the laser aperture is labelled, there is thus a yellow picto-

gram label besides the nozzle. The only source for dangerous

laser exposure is from the nozzle; the protective casing is de-

signed not to leak laser emission in any other place. With in-

tended use, there is no raised danger for laser exposure when

accessing the display controls. A remote interlock connector is

not required for handheld instruments. There are no service

panels, viewing optics or scanning elements; requirements for

these objects are thus not applicable. There shall be a me-

chanical attenuator/beam stop available to make it possible to

block the beam from the nozzle temporarily. The stop is re-

leased with the instrument enclosed Calibration Unit, which

also makes double duty as a dust cap. Class 3B is one of the

most severe classes; meaning that it is easy to permanently

harm the eye when the product is not used properly. A class

3B product is not suited as a consumer product since the op-

erator needs to be trained to use proper procedures to avoid

eye damage. A safety interlock is needed to ensure that only

trained operators use the instrument. A software requirement

solves this; the operator needs to login with a PIN number to

use the instrument. The software also turns the instrument off

Serstech 100 Indicator User Manual Vers.5.4.2

when inactive and a new login with PIN number is required.

Ensure the beam is always terminated at a suitable non-spec-

ular (i.e. non-mirror- like) surface. Do not direct the beam at

other people or into areas where other people unconnected

with the laser work may be present. Refer to the International

standard EN 60825-14 users’ guide for guidance on identifying

and controlling hazards associated with laser use.

Always ensure the invisible laser is turned off when

changing measuring accessories, e.g. from point-and-

shoot adaptor to the vial holder.

WARNING: Exposure to levels of invisible laser energy above

the MPE can be harmful to the eye. The minimum safety dis-

tance (Nominal Ocular Hazard Distance, NOHD) is 100 cm

from the invisible laser aperture to avoid exposure to levels

above the MPE. The output power is 300 mW at 785 nm. Al-

ways avoid exposure to the beam. Use administrative controls,

engineering controls, and/ or laser safety glasses to avoid ex-

posure to invisible laser radiation within the 100 cm hazard

zone. Use invisible laser safety eyewear of an optical density

(OD) greater than 3.

WARNING: Scanning a thermally sensitive material may

cause burning of the target. If the sample is contained in a

tightly sealed vessel (e.g. a capped vial), pressure may build

up during the scan, causing subsequent explosion of the ves-

sel.

The purpose of the different adaptors is to keep the sample at the proper distance from

the laser focus point. If the laser focus ends up too far inside the sample, the Raman signal

will be attenuated and result to a low quality or unusable spectrum. On the other hand, e.g.

Serstech 100 Indicator User Manual Vers.5.4.2

if a container wall is thicker than 4 mm, the focus point will end up on the container wall and

you will sample the container material instead of its content.

1. If the User measures through a glass or plastic container with 1.5-4.0 mm thick walls

use probe tip (10. in the picture above) without any adaptor mounted. The laser focus

will then be located 4.5-5.0 mm from the tip and therefore will end up inside the sample.

2. If the User measures through the standard sample vial with 14.8 mm outer diameter and

1.3 ±0.2 mm thickness, the laser will point 0.1-0.9 mm from the vial interior wall and 14

mm from the bottom of the vial inside the vial holder. Therefore, the vial must be filled

up to 2 mL at least so that the laser focus ends up inside the sample and not in the air.

3. If the sample is less than 2 mL use the insert to raise up the vial inside the vial holder.

The laser focus will point 0.1-0.9 mm from the vial interior wall and 2 mm from the vial

bottom. Minimum sample volume is approximately 0.4 mL.

4. With the point and shoot adaptor the focus will point approximately 0.2 mm from the

adaptor tip. That's why the point and shoot adaptor is appropriate to use when measur-

ing though a thin plastic bags or flush to a solid surface of the sample.

5. If the container has 1.0-1.5 mm thick walls use the bottle adaptor.

NOTE: It is very important to reduce stray light from entering the instrument as much as

possible, e.g. by covering the container with a black cloth unless the User uses the vial

holder adaptor. It is also recommended to use the auto-exposure mode. The amber glass

vessels and fogged plastic material will reduce the quality of the signal and thus the ob-

tained spectrum. The signal quality may be also reduced for the opaque samples, e.g. pow-

ders because of the sample depth (affected by factors as the grain size), fluorescence,

sample actual Raman response etc. However, for transparent, non- fluorescent liquid sam-

ples there are a much wider margin.
