LIBS FOR ON-LINE MEASUREMENTS
LIBS Sorts Materials and Provides Quality Control
Tough places need tough solutions. The Trakker™ is designed from the ground-up to give continuous, reliable LIBS measurements in an industrial environment. Unique features designed into the Trakker™ include:
Laser System
The Trakker™ comes with a pair of powerful Nd:YAG lasers operating at the fundamental frequency of 1064 nm. These lasers create the analytical plasma that is at the heart of the LIBS instrument.
 |
150+ mJ / pulse, 20 Hz repetition rate |
 |
Expected time between maintenance: 40,000,000+ shots |
 |
Redundant systems means no downtime |
 |
Automatic switching between laser systems during maintenance |
 |
Simple and fast maintenance |
 |
Few consumables |
 |
Flashlamp change approximately monthly |
 |
Deionizer cartridge change every 6 months |
Optical System
The optical system aboard the Trakker™ is designed to rapidly scan across samples and accurately collect light from the LIBS plasma to determine concentrations of elements.
 |
Unique optical delivery allows scan to sweep samples with a minimum of moving parts for high reliability |
 |
Rapid auto-focus delivers consistent energy on-target for greater precision |
 |
Sample lighting and high-resolution video facilitate auto-focus |
 |
Optics protected from the environment by on-board optical purge supplied with filtered, clean air |
 |
Automatic alignment and switching between lasers |
 |
Large collection optics maximize optical throughput and sensitivity |
Detector System
The detector system on-board the Trakker™ is optimized for the application. Examples of detector systems include:
 |
Dedicated PMT detectors for particular elements requiring high sensitivity |
 |
Rugged diode arrays |
 |
Intensified CCD cameras coupled to spectrometers fit-for-purpose |
 |
Real-time energy monitoring and control of lasers |
 |
Specialized LIBS algorithms interpret detector signals, track abundances of elements, and correct for matrix effects |
 |
The detection system should be periodically calibrated using built-in routines |
Control System
The analysis and control system on-board the Trakker™ is designed to work with existing process control and engineering analysis systems. This means that LIBS signals corresponding to particular compounds can be:
 |
Reported on an instrument screen |
 |
Output as 4-20 mA signals |
 |
Output as 0-5 V signals |
 |
Delivered over an internet connection |
Choices between the data delivery methods must be made before purchase and configuration of the system. System control is accomplished through an embedded real-time computer system.
Diagnostic System
The Trakker™ features an on-board diagnostic system designed to easily find and report trouble with the instrument, or otherwise report system status.
 |
If an internet connection is available, the diagnostic system can be configured to automatically report instrument health and status to a remote station for monitoring |
 |
Reduces maintenance cost and downtime by rapid alerting to potential problems |
Mechanical and Electrical
 |
Pumps and service equipment on board the Trakker™ are low-maintenance. |
 |
Electrical system designed for 220 or 440 V input (chosen upon purchase) |
Enclosure
 |
The Trakker™ instrument is designed in a rugged, weatherproof enclosure. |
 |
On-board heating and cooling control the environment inside the instrument to protect sensitive components |
Safety
 |
The Trakker™ is effectively a Class 1 laser product as the plasma / material interaction area is shielded from direct viewing.
