INTRODUCTION
Vulcan 84 is the first automated workstation combining the two essential steps of sample preparation – Digestion and Work-up. It is capable of automatic and precise addition of acids and reagents and monitoring temperature of Teflon® coated graphite hot blocks. During the process Vulcan 84 can handle various events such as sample mixing, levelling, cooling and transfer which simplify the critical tasks of sample preparation.
Vulcan 84 is a complete solution for automated sample preparation which accepts samples and returns prepared autosampler racks ready to be analysed. It also brings in:
- Error-free multi-time computerised acids and reagents addition for up to 84 samples
- Unattended multi-ramp precise and uniform heating of samples
- All plastic construction enables contamination-free digestion
- Freedom from manual handling of acids
- Unattended operations make effective use of skilled manpower
- Saves prime lab space with smart inbuilt fumehood
- Substantial cost savings in sample analysis
- Tracking, tracing and documentation of sample preparation processes
Vulcan 84 is available in several configurations from basic reagent delivery to automated digestion and work-up. It can easily be customised for your applications needs.
- Hot Blocks (QBlock Digesters)
o Rated to 230°C and can even handle HClO4 digestions
o Two QBlocks controlled independently and simultaneously
o Each QBlock accepts 42 x 50ml sample vials
o Teflon® coated graphite block and housing to prevent contamination
o Effective sample cooling during and at the end of the digestion process
o Accepts polypropylene, glass and Teflon® vials
- Acid and Reagent Delivery
o Syringe-based accurate and consistent delivery
o Six dedicated lines
o Capable of handling corrosive acids like HF and HClO4
o Deliver reagents and acids as required by each sample in a single run, thus can handle multiple types of samples at one time
o Internal standard addition possible
o Samples levelled up to volume after digestion with the help of level sensor
o Vigorous mixing through rapid stream of air bubbles
o Two-chambers wash station for cleaning the probes between two sample runs
o Accepts and prepares autosampler racks from various vendors
o Possibility of multiple dilutions for one sample
· System Enclosure
o No metal parts, all plastic construction suitable for trace level sample preparation
o Built-in fumehood with laminar flow exhaust for acid fume removal
o HClO4 ready system enclosure
o Positive air pressure in electronic section prevents acid corrosion
- Diligent Software Control
o Easy-to-build digestion recipe with functional steps like reagent addition, heating, stirring, sample transfer, washing and autosampler rack preparation
o Easy-to-set automation functions resulting in quick optimisation of the whole process
o Accepts rush, urgent or stat samples during the run
o Estimates and displays digestion process time and progress
o Prompts when reagent bottles need replacement
o Process documentation capability
