Accessories for Atomic Absorption

System 5000 Graphite Furnace

The GBC System 5000 is an automated graphite furnace system which may be used with any GBC AAS and provides determination capability to sub-ppb concentrations for most elements. The furnace system includes the GF5000 graphite furnace power supply and workhead plus the PAL programmable automatic sample loader. The system is controlled by the AAS system software.

Use ESV to watch your sample inject, dry, ash and even atomise during the furnace program. Method development has never been this easy. ESV comes standard with the SavantAA Zeeman and SavantAA Σ and is optional with the SavantAA. Contact us to learn more.

The furnace assembly includes graphite tube (complete with platform for reduced chemical interferences, if required) mounted in an enclosure with quartz windows.

It can be used in conjunction with any GBC AAS. Installation is simple, with a permanent attachment to the power supply by an umbilical cord which contains all necessary connections including gas, cooling water and electrical supplies. The temperature range of ambient to 3000° C is computer controlled with a maximum ramp rate of 2000°C/sec.

PAL Furnace Autosampler

PAL Furnace Autosampler The sampler is an essential component of the furnace system and each accommodates around 40 samples and 10 pre-mixed standards, plus one stock solution for automatic mixing of up to 10 standards. Multiple carousels can be used in an analysis.

Dispensed volume is up to 100 µL, programmable in 1 µL increments. Program options include automatic mixing of standards, automatic injection of chemical modifiers, multiple injection, heated injection, plus complete re-slope, re-calibration, check sample or spike recovery routines.

HG3000 Hydride System and EHG3000 Electric Cell Heater

The HG3000 Hydride generator forms part of a complete hydride system which can be used in conjunction with any GBC AAS for trace level analysis of the hydride forming elements (arsenic, selenium, antimony, bismuth, tellurium, tin, germanium and lead at parts per billion concentration level), and mercury by the cold vapour method. Detection limits of 1 ppb are routinely achievable. Typical sample throughput is around 60 samples per hour taking three replicate measurements, with a typical precision of 1%.

The quartz cell used for hydride analysis can be heated by flame, or by the optional EHG3000 electric cell heater. The EHG3000 provides a temperature controlled electric heating blanket to heat the quartz cell, and includes power supply, temperature controller and workhead. The EHG3000 provides more accurate temperature control than is possible with flame heating.

MC3000 Mercury Concentrator

The MC3000 mercury concentrator is used in conjunction with the HG3000 and adds parts per trillion capability to the hydride system for the analysis of mercury vapour, using a gold amalgam as the concentrating medium. The MC3000 consists of a power supply and workhead with built in gold foil trap and a quartz absorption cell. It is controlled by the AAS software, which provides programmable load time, number of replicates, flush time and clean.

SDS-720 Sample Delivery System

The SDS-720 is an XYZ autosampler system for flame AAS, ICP or ICP-MS. It can be used for flame analysis, hydride generation, mercury cold vapour analysis and with the MC 3000 mercury concentrator. It can also be used with the Autosipper with the Cintra 2020, 3030 or 4040.

The SDS-720 is a precision engineered X-Y-Z autosampler. The SDS-720 provides accurate and fast analysis due to its durable, simple, adaptable, reliable and sturdy design. Supplied with sample racks to hold 180 sample vials each of approximately 14 mL and a standards rack to hold 10 standard vials each with a volume of approximately 20 mL. PTFE and PEEK is used to provide a metal free liquid flow path. Variable continuous flow sample probe rinse station with peristaltic pump minimizes sample contamination and carryover. An inert spill rack which prevents any solution inadvertently spilling over the autosampler or your laboratory.

The SDS-720 is now faster than the superseded model and provides unmatched productivity with full random access capability from a small footprint.

A built in peristaltic pump provides trouble free continuous stream of clean rinse solution.
