System Design

• The PinAAcle 900Z (THGA) system incorporates the spectrometer and the THGA components only on a single instrument. 
• Monochromator:  Littrow design with motorized drive for automatic wavelength selection and peaking.
• Wavelength Range: 190 – 900 nm. Diffraction grating: 1800 lines/mm blazed at 236 nm and 597 nm.
• Spectral Bandwidths:  User selectable automatic slit widths of 0.2, 0.7 and 2.0 nm at their optimized slit height.
• Detector:   Wide-range segmented solid-state detector, including a built-in low-noise CMOS charge amplifier array.
• Automatic Lamp Selection:  8-lamp mount with built-in power supplies for PerkinElmer® cableless Lumina™ hollow cathode and patented electrodeless discharge lamps. Computer-controlled lamp selection and alignment via WinLab32™ for AA software. Lamp elements and recommended operating currents are automatically recognized and set when using Lumina hollow cathode lamps.

Background Correction

• Longitudinal AC Zeeman-effect background correction using a modulated 0.8 Tesla magnetic field oriented longitudinal to the optical path. The magnet is automatically switched on during the atomization step only. Rollover detection is built-in. 

Graphite Furnace Atomizer

• Built-in fully computer-controlled Transversely Heated Graphite Atomizer (THGA) – the graphite tube is transversely heated, providing a uniform temperature profile over the entire tube.

• An external protective gas stream around the graphite tube prevents the entrance of outside air to maximize tube life. An internal purge gas goes through the graphite tube to remove the volatilized matrix vapors during drying and thermal pretreatment. The two gas streams are computer-controlled independently. Pneumatic opening and closing of the furnace for easy tube change.
• Common Furnace Features:  Analytical programs with up to 12 steps can be set up. Each step can be programmed with the following parameters:
  • Temperature:   Ambient up to 2600 °C (up to 3000 °C with PinAAcle 900H) in steps of 10 °C
  • Ramp Time:   0 to 99 s in steps of 1 sec
  • Hold Time:  0 to 99 s in steps of 1 sec
  • Internal Gas Flow:  0 mL/min (gas stop), 50 mL/min (mini-flow), 250 mL/min (full flow); can be switched over to another type of gas (alternate gas).
  • Furnace Opening and Closing:  Pneumatically-operated by software command.
  • Required Inert Gas   Argon – inlet pressure 300 kPa (3 bar) minimum. Maximum gas consumption is 700 mL/min.
  • Water Coolant  A circulatory cooling system is recommended and can be chosen for the PinAAcle 900T, 900Z and 900H systems. When operating the 900T/Z/H furnace systems without the  circulatory cooling system, cooling water meeting the following specifications should be used: sediment-free drinking water; 20-40 °C; flow rate not less than 2 L/min; pressure between 2.5 and 4.5 bar; pH between 6.5 and 7.5; hardness not greater than 14°dH or 100 ppm.

Furnace Autosampler

• Furnace Autosampler:  Sampler Table: Installed in front of the furnace unit. Removable sample tray with 88 and 148 sampling positions for sample and reference solutions and 1 overflow container for  pipette washing. Minimum sample requirement: Ca. 0.1 mL.
• Dispensable Volume:   Sample and Reagent: 1-99 μL, selectable in increments of 1 μL.Max. dispensable volume is 99 μL (sample volume + reagent volume). Flushing volume is fixed at 1.3 mL.
• Electronics:   The autosampler is powered from the spectrometer and is software-controlled.

Data System

• Data Control System:  Complete PC control using WinLab32 for AA software operating under the Microsoft®Windows® 7. Provides complete control of the instrument and its major accessories plus data handling and storage.
• Data Handling:   Instrument readings linear in absorbance (-0.500 A to +2.000 A), concentration or emission intensity with continuously variable scale expansion from 0.01 to 100 times. Integration  times operator-selectable from 0.1 to 120 sec in increments of 0.1 sec. Reading modes include time-averaged integration, non-averaged integration (peak area), and peak-height measurement. Includes built-in statistics. Up to thirty (30) standards and a choice of proven calibration equations. Reslope of the analytical curve using a single operator-selected calibration standard. Built-in Ethernet interface for computer connection and use of optional accessories. Data collection time of up to 20 mins.
