Avio™ 200 Newest ICP Optical Emission Spectrometer of PerkinElmer   

PERFORMANCE VALUE AND EASE OF USE IN ONE COMPACT PACKAGE 

Capable of handling even the most difficult, high-matrix samples without dilution, the Avio™  200 system brings a whole new level of performance and flexibility to ICP.

What's more, that unprecedented performance comes with unparalleled ease-of-use. Unique hardware features and the industry’s most intuitive software combine to make multi- element measurements as easy as single-element analyses.

The smallest ICP on the market, Avio 200 offers the most efficient operation, reliable data, and lowest cost of ownership by delivering:

• The lowest argon consumption of any ICP ( The Avio 200 operates with a plasma flow of 8 L/min and a total argon gas flow of 9 L/min, compared to 21 L/min required by other systems)

• The fastest ICP startup (spectrometer ready in just minutes from power off)

• Superior sensitivity and resolution for all elements of interest

• The widest linear range with dual viewing technology

Reliable. Capable. Affordable. The Avio 200 is everything you’re looking for in an ICP.

Double Spectrometer

The Avio 200 ICP-OES uses a unique  double-spectrometer optical system. This design results in a high-speed, high-

light-throughput optical system offering excellent resolution, all in a compact  system. The sealed optical system can be purged  with nitrogen  for low UV (165-190  nm) performance.

Echelle Spectrometer

The high-dispersion  echelle spectrometer has a focal length of 0.3 meter and a Stigmatic Littrow configuration. The echelle grating used for dispersion has 79 lines/mm with a blaze angle of 63.8 degrees.

Parameters

The spectral range  is 165-900 nm with resolution of < 0.009  nm @ 200 nm.

Plasma Viewing

The system incorporates  a vertically oriented  plasma with complete  dual-viewing optics under computer and software control. Any wavelength can be used in the radial, axial or mixed viewing modes in a single method. With the patented Dual View capabilities of the Avio 200 system, viewing of the plasma is accomplished  by computer control of a mirror located in the optical path  and allows selection of axial or radial view and adjustment of the plasma viewing in both the vertical and horizontal planes.

Detector

The UV-sensitive, dual backside-illuminated Charge-Coupled Device (CCD) array detector is cooled directly using a single- stage  integrated Peltier cooler operated at approximately -8 °C. The detector has two photosensitive  segments containing  176 by 128 pixels. One section is used for analytical measurements, and the other  is a wavelength reference  section. The CCD-array detector collects both  the analyte and the nearby background information  in a single spectrum,  allowing for simultaneous background correction and providing improved precision and analytical speed.

Dynamic Wavelength Stabilization™

The wavelength reference  section of the detector monitors a small portion  of the neon  spectrum  in order to create a dynamic wavelength scale used to actively correct wavelength positions. The resultant  wavelength accuracy and reproducibility allows direct ‘on-peak’ measurements rather  than  time-consuming peak-search methods used in sequential  ICP systems

ICP System Specifications

RF Generator

The Avio 200 ICP-OES features  a fourth-generation 40 MHz, free-running  solid-state RF generator, adjustable  from 1000  to

1500  watts,  in 1 watt  increments.  The power  efficiency is greater than  81%  with < 0.1%  variation in output power stability. True Power Control maintains the plasma power  at the set point, even when changing  sample matrices. The compact  RF supply meets all FCC certification requirements for RF emission (Part 18 of FCC rules and regulations) and complies with EC and Class A requirements.

Its unique  Flat Plate™  plasma technology  generates and maintains a robust,  matrix-tolerant  plasma with approximately half the argon consumption of helical load-coil systems.

Plasma Ignition  and Extinction

Plasma ignition is computer-controlled and totally automated. The plasma can be ignited automatically  at a user-determined time and turned  off automatically  after an analysis.

Safety Interlocks

For user safety and system protection, the system constantly monitors  water  flow, shear gas pressure,  argon  pressures, sample-compartment door closure and plasma stability,

and displays the interlock status on the computer screen as graphic symbols. If an interlock is interrupted, the plasma will immediately and safely shut down.

Cooling  Water

A water-recirculating cooling system is required,  with approximately 4 L/min flow capacity at 310 to 550 kPa and a temperature between 15 °C and 25 °C.

Gas Flow Controls

Argon  Flow

Computer-controlled solenoid valves are used to regulate  the flow automatically  within the range  of 8-20 L/min in 1 L/min increments  for plasma argon and 0 to 2.0 L/min in 0.1 L/min increments  for auxiliary argon.  A mass-flow controller is supplied with all systems for the nebulizer argon flow and is variable between 0 and 2.0 L/min in 0.01 L/min increments.

PlasmaShear™

A compressed-air shear gas (18-25 L/min) is used to remove the plasma tail from the optical path,  minimizing interferences and extending  the dynamic range.  PlasmaShear provides a maintenance-free and lower-cost approach to removing the cooler plasma zone.

Sample  Introduction System

Torch/Torch Mount

A unique,  demountable torch design using one-piece  quartz  tubing for plasma and auxiliary gas flow is supplied. The standard torch includes a 2.0-mm  i.d. alumina injector for full corrosion resistance to all acids, including hydrofluoric and aqua regia. A variety of

other injectors are available. The externally mounted spray chamber is integrated into an easily removed sample-introduction cassette. The sample-introduction cassette  can be adjusted  (with the plasma on) for maximum performance in different matrices. No tools are required for torch or sample-introduction cassette  removal.

Spray Chambers

Instruments  can be ordered  with a Ryton®  HF-resistant Scott-type or a glass cyclonic spray chamber.  A variety of other spray chambers  are available.

Nebulizers

The Avio 200 can be ordered  with a cross-flow or glass concentric nebulizer.  The cross-flow design with GemTips™  is corrosion- resistant  (sapphire/ruby tips in a PEEK body). The system can routinely handle  50%  (v/v) solutions of HCl, HNO3, H2SO4,

H3PO4, 20%  (v/v) HF, and 30%  (w/v) NaOH. Additional nebulizers are available.

Peristaltic Pump

The integrated four-channel, computer-controlled pump has variable speeds from 0.2 to 7 mL/min in 0.1 mL/min increments, using 0.76 mm (0.030 in.) i.d. tubing.  Software features  include FastPump™  and SmartRinse™, which dramatically improve the sample rinse-out and analysis times.

Spares Kit

A spares kit of common  replacement items is included.
