GBC manufactures a full range of atomic absorption sampling accessories to cover all analytical requirements. They can be fitted to any GBC AAS, except the SavantAA Z enduro.
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.
GF 5000 Graphite Furnace
GF 5000 Graphite Furnace 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 Auto Sampler
PAL Furnace Auto Sampler 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.
SDS3000 Sample Delivery System
The SDS3000 is an X-Y-Z auto sampler system for flame AAS, ICP-OES or ICP-MS. It can be used for flame analysis, hydride generation, mercury cold vapour analysis and with the MC3000 mercury concentrator. It can also be used with the Autosipper with the Cintra 2020, 3030 or 4040.
The SDS3000 is a precision engineered X-Y-Z auto sampler. Designed and fabricated by GBC Scientific Equipment, this affordable auto sampler provides accurate and fast analysis due to its durable, reliable and sturdy design. Supplied with four sample racks to hold 240 sample vials each of approximately 14 mL and a standards rack to hold 10 standard vials plus a blank each with a volume of approximately 50 mL. PTFE and PEEK material 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. Software controls include rinse time, delay time, number of replicates, rescale rate, recalibration rate, measurement time and analysis order. Full random access capability is standard. Upto to 360 samples can be loaded using 7 mL tubes.
An optional auto dilutor will soon be available. The syringe type auto dilutor will be cleverly incorporated inside the SDS3000.
Atom Trap Enhance sensitivity for certain elements using the GBC Atom Trap. The Atom Trap is a flame-heated quartz cell which is placed in the optical path. It enhances sensitivity by providing a longer residence time for the analyte in the excitation zone.
