3B invisible laser. This manual describes the basic functions of the instrument. Functions may be different depending on the hardware and/ or software version in the device. The manual covers Arx devices with embedded software functionality version 5.5.0 or later.
For a safe handling Serstech AB recommends Users to do as following: § Store the product in a dry and ventilated environment. § Do not attempt to repair the product by yourself, contact SERSTECH or your SER- STECH reseller for service matters.
United States, other countries or both. Support In case the User should requires technical assistance, should contact its SERSTECH reseller. If the User questions cannot be answered immediately, the reseller will forward all queries through the appropriate channels to ensure a rapid response.

handheld instruments. There are no service panels, viewing op- tics or scanning elements; requirements for these objects are thus not applicable. There shall be a mechanical attenua- tor/beam stop available to make it possible to block the beam from the nozzle temporarily. The stop is released with the instru- ment enclosed Calibration Unit, which also makes double duty as a dust cap.
The Peli case, interior view. Accessories There are different accessories for different sample applications: 1. Vial holder 2. Vial 3. Vial holder rise 4. Strap attachment 5. Small-amount adapter 6. Calibration cap Vial holder Vials can readily be analyzed without any adapter. However, there is always a risk that stray light maty enter the spectrometer and disturb the measurement.

holder both a beam block that ascertain laser safety and effective protection from stray light is obtained The holder accepts 4 ml standard vials with 14.8 mm outer To mount the vial holder, simply snap it in position on the probe tip. Place the vial into the vial holder.
Page 11
When the vial is in position start the analysis. WARNING: Scanning a thermally sensi- tive material may cause burning of the target. If the sample is contained in a tightly sealed vessel (f.eg. a capped vial), pressure may build up during the scan, causing subsequent explosion of the vial.
Page 12
The insert is placed at the bottom of the vial holder to allow the analyzing laser beam to be focused onto the lower region of the vial. First place the vial insert in the bottom of the vial holder Then place the vial on top of the vial insert.
Page 13
When the vial is in position a part of the vial will be raised above the vial holder and it is not possible to screw on the cap of the vial holder. Start the analysis. NOTE: It is very important to reduce stray light from entering the instrument as much as possible, f.eg.
Small sample adapter Any type of solid sample can be analyzed using the Arx instrument without any adapter. However, it may be hard to focus the analyzing beam onto very small samples. The small- amount adaptor has a conical shape and a small aperture. This makes it easier to point the analysing beam towards small samples.
USB Cable The supplied USB cable is the connection cable between the Arx and a PC, used to access ChemDash 2.0. The USB cable is also used to connect the optional USB charger to the instrument.

Inconclusive Result: There is no spec- trum in the libraries that matches the sample spectrum. You may want to re-test the sample while paying close attention to that the sample is correctly positioned at the in- struments focal point and the instrument is not exposed to strong ambient light.
Page 29
The user has the possibility to add a label to the measured substance. The Label name can be selected by moving up/down with the help of the ar- rows and selecting the desired letter by clicking OK button. If the result is considered to be not sat- isfying, the user has the possibility to per- form an advanced scan by selecting the Go to advanced scan option.
Page 30
There is also the possibility to view the Substance details by selecting this op- tion. The identified substance will be displayed. Some of the properties, such as match- ing percentage (94%), CAS number and some GHS details will be displayed. After seeing all desired details, the user must press Back button to return to the measurement screen.
There is also the option of Adding to a local library the newly measured sub- stance. After selecting this, the user must give a name to the library using the key- board on the screen, moving up/down with the arrows. If the result seems not clear enough, the user has the possibility to Restart the Scan.

Before the measurement you will choose a reference substance from the spectra li- braries. The Arx instrument will analyze the sample and compare it with the chosen refer- ence. The result is binary, either Pass (OK) if the sample is similar to the reference spec- trum or Fail (not OK) if the sample is different.
Page 40
Select one or several libraries you will use for the analysis. These can be from the recent substances you have worked with or from the pre-existing libraries. Select the substance you want to verify by writing its name with the help of the keyboard on the right of the screen (you scroll up and down and if you want to se- lect that specific letter, you click OK)
Page 41
Once the desired substance is selected, the user must click on the lower button “Verify [substance name]”. Follow the different steps in the sample analysis: There is a warning regarding the laser activity. The lower progress bar shows the pro- gress of the current part of the scan pro- cess, beginning with the setting the laser temperature.
Verify analysis result 7.3.1 There are two possible outcomes from the Verify scan, either Pass (OK) if the sample is like the reference spectrum or Fail (not OK) if the sample is different. Pass screen is displayed if the analyzed substance spectrum has sufficient corre- lation with the reference spectrum, f.eg.
