| AAS Products |
| GBC is a world leader in the development and manufacture of atomic absorption spectrometers, with over twenty years of experience in supplying the needs of the global elemental analysis market. |
| SensAA |
| GBC Scientific Equipment introduces the latest Atomic Absorption Spectrometer, the SensAA. The SensAA is new in every aspect from the ground up - from its performance to its looks and functionality. It may be our low cost AAS but its performace exceeds many top of the range products in the marketplace. |
 |
PERFORMANCE
By improving the optics and electronics design the wavelength has been extended (175 to 900 nm). The D2 range has also been extended (175 to 423 nm) thereby enabling more elements to be analyzed using D2 background correction. The slit width is now adjustable from 0.1 to 2.0 nm in 0.1 increments thus effectively allowing 20 slit width settings with normal slit height plus 20 slit width settings with reduced slit height.
The SensAA series sets new pre-requisites wth the new Hyper-Pulse Background Correction that allows for more accurate interpolation of "Transient SIgnals" such as GF and HSA 3000 signals. The new GCM (gas control modeule) is fully interlocked with the new fully integrated Spray chamber/liquid trap for added safety.
The heart of the SensAA is the patented Application Source which addresses new levels of performance, simplicity and cost savings in AA spectrometry.
The SensAA offers touch screen technology and true uncompromised multi-element analysis, returning the highest integrity in results at a fraction of the cost of traditional means. Designed around simplicity, users no longer need to change lamps when changing elements, enabling seamless operation. Application Source offers dramatic savings in source lamp costs and the high intensity D2 lamp offers unrivalled lifetime performance with enhanced operation of up to 1000 hours, even at full current.
FUNCTIONALITY
The SensAA is supplied with an inbuilt P4 computer and touch screen technology. A large 15" colour screen allows clarity of use and also ease of inputting data and executing commands to the SensAA software. No more keyboards or mouse wires to get tangled with acidic sample solutions. Point and analyze! An inbuilt software keyboard is also available where text is required to be entered by using standard Windows XP as the operating system then any Windows software package can also be loaded into the SensAA further extending its fuctionality. As always GBC AAS accessories are interchangeable and can be used on the SensAA.
LOOKS
The SensAA has a smaller foot print than the 932 spectrometer it supersedes. Add to this space saving the fact that the computer is already included inside the SensAA and the result is significant bench spacing. You can have 2 SensAAs in the space where 1 AAS and computer would sit.
A retractable sample holder is also been included free of charge.
The SensAA - Sensitive to the Touch, Sensitive to Your Environment, Sensitive to Your Analysis

| AAs Accessories |
| 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 Zeeman. |
System 5000 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 S and is optional with the SavantAA. Contact us to learn more. |
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 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. |

SDS-720 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 202, 303 or 404.
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 240 sample vials each of approximately 14 mL and a standards rack to hold 10 standard vials each with a volume of approximately 50 mL. Plastic sample and standard vials are supplied.
