AvaLIBS is a novel-design modular system which utilises Laser-Induced Breakdown Spectroscopy (LIBS) for the elemental characterisation of materials. The highly modular and versatile design adopted in AvaLIBS will appeal to scientists and engineers interested in developing LIBS technology for their particular application area. AvaLIBS is also well-suited for use in an academic teaching laboratory where ease of use and safety are of paramount importance.
AvaLIBS may be operated in “open-beam” mode as a Class IV laser system or fitted with one of a range of fully-interlocked modular sample chambers as a Class I laser system. In either configuration the system can be operated with the AvaLIBS Head held or mounted in any orientation offering further flexibility in the types of sample that can be analysed.
Features
- Modular and versatile design, suitable for laboratory and field applications
- High-efficiency plasma light collection optics (3 UV-Vis channels and 3 Vis-NIR channels)
- Laser options: 50 mJ 1064 nm laser (AvaLIBS-50) and 100 mJ 1064 nm laser (AvaLIBS-100)
- Gas purge feature (for connection to external inert gas supply – Argon, Nitrogen, Helium)
- Optional imaging camera for viewing the sample before, during and after LIBS analysis
- May be operated with one of a number of removable, modular sample chambers (to Class I laser safety standards) or without (Class IV “open beam” configuration)
- Optional vertical support stand with height adjustment (facilitates operation of AvaLIBS Head in vertical orientation – with or without sample chamber)
- Up to six spectrometer modules may be installed (approx. 185 – 900 nm)
- External laser power supply easily disconnected to facilitate transportation
- May be operated with laptop PC or other suitable device running Microsoft Windows

AvaSoft operating software
The AvaSoft software controls the exact timing between the laser pulse and the start of the integration time. The timing is controlled by the laser or external pulse generator and synchronized with the AvaSpec spectrometer by running the spectrometer in external trigger mode. In this mode, the spectrometer receives a TTL-input signal from the laser, or simultaneously with the laser. The integration time delay is synchronized with this input signal.The AvaSoft software allows averaging, setting of integration time delay and integration time.The saved data can be imported directly into the Specline analytical software package (see section software).

AvaLIBS Modules – an alternative method of configuring a LIBS system
AvaLIBS modules offer a convenient and flexible method of configuring a LIBS system. Six channel (AvaLIBS-module-6) and eight channel (AvaLIBS-module-8) versions are available. Each optical channel is connected to an individual spectrometer using a single-core optical fiber. This allows the user to select one or more spectrometers according to their needs. In addition to the 50 mJ and 100 mJ laser described below, the AvaLIBS modules may be used with a variety of other lasers using an appropriate adaptor plate (contact us for further details).

| Example configuration: AvaLIBS-module-8, 100 mJ Ultra laser, AvaLIBS-SC-3 sample chamber, 8 AvaSpec 2048-LIBS spectrometers |
