Detection Limits

GAS CHROMATOGRAPH GC600

Full range of detectors with excellent sensitivity and linearity ranges: FID, TCD, ECD, NPD and MS.

Cold septum, purgeless injector eliminates septum bleeding so septum purge is not required and column integrity is maintained. Leak tight injector prevents loss of volatiles, improving detection limits and reproducibility. Use of a straight liner enables fast transfer of the high boiling analytes to the column head. No possibility of back diffusion of atmospheric oxygen or water through the septum purge flow, which could oxidise or hydrolyse very labile samples in the hot GC injector.

Pressure resolution: 0.0015 PSI. Extended pressure and flow operating ranges deliver a choice of true flow or pressure programming. Up to 5 ramps and free selection of carrier gas reduces analysis time.

Low inertia, high precision oven (±0.1°C displayed) with an expanded temperature range allows for ultra fast heating and cooling. It is isolated in a forced-air circulating chamber for better temperature stability.

Upgraded oven-flap design achieves optimal temperature control.

PG integration software provides full automation and also controls the auto injector, allowing any combination of injector sequences and providing a simple tool for data acquisition, processing and report generation.

ATOMIC ABSORPTION AA500FG

The temperature of the transversely heated graphite tube is accurately controlled by means of a precision feedback system. Pyrolytically coated platform tubes are supplied as standard to improve the performance and eliminate many analytical problems associated with this technique.
The flame atomiser position is fully controlled by the embedded computer system and AA-Win Pro software.
Three flame options are available to the user with the Air/Acetylene being the standard configuration. This flame can be used for nearly all standard elements while the N₂O/Acetylene and the Air/LPG (Natural gas) are available as an option for the more demanding of elements. All three flame configurations offer coded burner for full safety protection.
Standard Features

•  Embedded PC system built into the instrument as standard on all configurations. Pre-installed UV-Win Pro software, user manuals, cook book and Windows 7 professional operating system.
•  UV-Win Pro software provides full control of the instrument and autosampler with easy method change for each technique.
•  Automatic 8 Hollow Cathode lamp turret controlled and optimised by the AA-Win Pro software. Operating lamp current and warm-up lamp current can be individually controlled to eliminate drift commonly associated with lamp warming.
•  D2 lamp background correction system fitted as standard to all configurations. High energy D2 lamp and adjustable beam splitter mirror are optimised by the AA-Win pro software.
•  Self Reversal background correction system fitted as standard to all configurations. The high performance background system uses the same hollow cathode lamp as installed for the analysis. Minimum extra components are required and optical alignment is very simple. Self Reversal can be used for any element at any wavelength making it extremely versatile.
•  High precision minimal optics ensures maximum light throughput to the computer controlled Czerny-Turner monochromator.
•  A universal autosampler is available as an optional accessory which is conveniently mounted on the front of the AA500 instrument.
•  Absorption and Emission modes are standard features in the AA WinPro software as well as peak height, peak area, sequential and manual integration modes.

Flame Atomiser Features

The flame atomiser offers three flame options:
Air/acetylene is the standard configuration with the N2O/acetylene and Air/LPG as options.
Air/Acetylene  

•  The Air/Acetylene flame uses a 100mm single slot burner for the standard configuration.
•  The high sensitivity (Cu 2ppm >0.280abs) is due to the efficiency of the fixed position glass nebuliser fitted as standard. An acid resistant replacement is available as an option.
•  The flame can be easily set from blue lean flame through stoichiometric to fuel rich by means of computer control.

N20/Acetylene

•  The N2O/Acetylene flame uses a 50mm single slot burner and is available as an optional extra.
•  This flame configuration is used to measure elements less prone to ionization such as: Aluminium, Tin, Titanium, Calcium, Vanadium and Molybdenum.
•  Switching from Air/Acetylene to N2O/Acetylene to Flame Off is fully controlled by the AAWinPro software.

Air/Propane (LPG)

•  This flame uses a 3 slot burner and with the low pressure requirement it is also much safer to operate.
•  Due to the low temperature of the flame it is ideal for analysing alkali metals such as: Potassium, Sodium and Lithium, especially when used in the emission mode.
•  Some remote areas of the world have difficulty obtaining Acetylene gas of a high enough purity to operate the flame correctly, LPG can give a real alternative and offer comparable results for most elements throughout the wavelength range.

Safety Features

•  Pressure monitoring for all gases.
•  Burner Identification
•  Flame sensor
•  Drain Trap level Sensor
•  Gas Leak Detector
•  Over Pressure in Premix.
•  Safety Cut off Switch.

Graphite Atomiser Features

• The integrated Graphite Furnace Atomiser is available in two instrument configurations.
•  In the AA500G instrument the graphite furnace head is fixed into the light path so alignment with the optical path is simple and accurate.
•  In the AA500FG instrument the graphite furnace head is fixed behind the flame atomiser assembly and is motorised into position by a simple operation in the AAWinPro software. The positions for the flame and graphite are saved making it easy to swap between modes for different analysis.

Features

•  The temperature of the transversely heated graphite tube is accurately controlled by means of a precision feedback system and has been designed to reduce analytical problems normally associated with this type of technique.
•  Pyrolytically coated graphite tubes are used as standard and are manufactured to improve performance as well as increase the analytical life.
•  Platform graphite tubes are supplied as standard and will accept volumes up to 20µl. Non-platform graphite tubes are also available as an optional extra.
•  Up to 10 heat stages are available for the programming of the graphite atomiser. These can be set and stored within the AAWinPro software.

•  The graphite tube is efficiently cooled by an additional water circulation system (supplied separately).

Safety Features

•  Argon Gas pressure Sensor
•  Water flow sensor
•  Over Temperature Sensor
•  Broken graphite tube protection.

ATOMIC ABSORPTION SPECTROMETER pg990

The PG990 Atomic Absorption Spectrophotometer is a versatile entry level instrument with a computer controlled Air/Acetylene flame for general laboratory requirements. Due to its high sensitivity and excellent performance the instrument can be used for a wide range of applications including:

• Agricultural
• Clinical
• Environmental
• Food
• Metal
• Mining
• Geological
• Petrochemical
• Pharmaceutical

Features

• The instrument has a motorised 8 hollow cathode lamp turret which allows the automatic positioning and optimisation of each hollow cathode lamp by the software.
• The control of the gas flows for the fuel gas (C2H2) of the burner is also carried out directly from the software thus allowing optimisation of the instrument for the best analytical parameters for a selected analysis.
• Two methods of background correction are available. The first utilises a Deuterium Arc lamp and the second is the proven method of Self Reversal.
• High precision minimal optics ensures maximum light throughput to the computer controlled Czerny-Turner Monochromator.
• The location of the wavelength and peak selection is automatically controlled from the software.
• The spectral bandwidth is automated and is available with a choice of five slit sizes.
• The electronic parameters for the photomultiplier tube detector, the hollow cathode lamp current and the balancing of the absorbance and background energies are controlled from the software.
• The ignition of the flame is computer controlled and the various safety interlocks offer a very safe operating system.

Safety

• The flame conditions are continuously monitored and should the flow rates change, an audible alarm sounds.
• The pressure of the support gas (oxidant) is monitored constantly. If the pressure changes then the flow of the fuel gas will be stopped and the flame will be safely extinguished.
• A sensor monitors the level of liquid in the drain and will prevent ignition if too low. The flame will also be extinguished if the level of liquid in the drain changes significantly.
• A flame sensor monitors the flame and safely turns off the gas flow to the burner if the flame suddenly extinguishes.
• The burner is identified by a switch making it impossible to light without the burner being fitted.
• An emergency flame off button is installed in case a problem is observed. The flame can be extinguished safely.
