Delivery information
Prices exclude shipping costs. Stated shipping costs are to be expected. Deviations are possible. If transport costs are not specified, please ask separately for them.
The stated transport and packing charges apply to the most favorable route if transport and are to be understood as subject to verification due to unexpected cost increases. By reason of unpredictable events, cargo rates and delivery times can change at any time and therefore have to be adapted to the recent situation. Import formalities and possible customs charges will be borne by the purchaser. Incoterm coding according to Incoterms 2010: For persons who collect the devices themselves: EXW, for dipatch by sea: CFR, by air freight: CPT, other shipments: DAP. Note for international shipments: A proof of preference/EUR1 will not be issued by us. When self-collecting/ordering EXW from countries within or outside the European Union, 16% VAT will be retained as a deposit until we have received the corresponding confirmation of arrival/bill of delivery from the buyer.
Terms of payment
We do not accept payment by letter of credit, PayPal, etc. In each case the invoice amount is payable without deduction. Discount is not granted.

Narrow Beam Optics
Tue double beam all-reflective optics with unique Rotating Beam Combiner (RBC), alternately passes 100% of sample, beam and 100% of reference beam to the monochromator for low noise and better detection limits. All mirrors hard dielectric coated. All optics mounted in a completely sealed three dimensional cast aluminium Chassis for strength and reduced vibrations.
Monochromator
Czerny Turner :330 well focal length. Holographic diffraction grating, 1800 lines/mm, for greater resolution blazed at 240 nm. Wavelength range 185 -900 nm.
Seven von slits, 0.1, 0.2, 0.5 and 1.0 nm with full height and 0.2, 0.5 and 1.0 reduced height, for furnace operation. Selected wide range R446 multi-alkali photomultiplier tube.
Lamp Turrets
Eight Iamp automatic positioning turret (SpectrAA-400) or four Iamp manual positioning turret
(SpectrAA 300) both with SpectrAA lamp bases. The unique turret base stops the Iamp from sliding forward and eliminates corrosion prone flying leads and connectors. Electrical connection is made when the lamp is inserted directly into the base.
Compatible with:
Coded lamps for automatic element. recognition without adaptors
Multi-element coded lamps for automatic selection of next element in the sequence without rotating the turret
Economical uncoded lamps
High intensity Superlamps for best detection limits
Both lamp turrets feature:
Two Iamp power supply for operating Iamp and automatic warm up of next lamp in sequence
Pre-alignment of either 8 or 4 lamps
Automatic switch off of each Iamp after use.
SpectrAA Hollow Cathode Lamps
Electronically modulated for Narrow Beam profile for better sensitivity and extended lifetime.
Background Correction
High intensity deuterium background corrector standard. Range 185 to 425 nm to total 2.3 absorbance.
2 ms response for accurate correction of fast background signals. Electronic modulation with automatic attenuation. Lamp is mounted at the front for easy adjustment or replacement by the user without removing instrument covers.
Programmable Gas Control Option
Fuel and oxidant gas flows set from with closed loop feedback control.
Automatic changeover between air and nitrous oxide flames and automatic setting of gas flows for each element . Thirteen safety interlocks. lf any interlock (except the flame shield ) is violated, the Safety Tank
Extinguishes the flame with a burst of air, and shuts off both the acetylene and the oxidant. Separate flame-on and flame-off buttons.
Automatic Gas Control Option
Fuel and oxidant gas flows set manually with flow rotameters. Automatic changeover between air and nitrous oxide flames. Eleven safety interlocks. All interlocks must be satisfied before the flame is ignited. During operation, if any interlock (except the flame shield) is violated, the Safety Tank extinguishes the flame with a burst of air, and shuts off both the acetylene and the oxidant. Separate flame-on and flame-off buttons.
SpectrAA Safety System
No cables, adaptors, restraining wires or tools required.
Interlocks on:

Burner correctly fitted
Liquid trap full
Nebulizer bung in place
Pressure relief bung in place
Flame shield in place

*Programmable gas control only
Separate upper and lower flame shields and double skinned extraction chimney protect against UV and heat, while allowing adjustment of all burner controls. Igniter button is not used for both flame an and flame off.
Mark VI Flame Atomization System
o Standard features:
o Solid polypropylene Mark VI spraychamber
o Rapid removal and disassembly without tools, for cleaning or to switch to furnace operation
o Removable twin-head mixing paddles
o Externally adjustable impact bead
o Dual position Hi-vac nebulizer with inert platinum/iridium capillary and tantalum venturi
o Integral liquid trap with magnetic float interlock
o Incoloy Mark VI air-acetylene burner with Teflon corrosion shield
o Burner rotation through a full 90°
Options:
o Mark VI nitrous oxide acetylene burner
o Teflon impact bead for HF applications
o Adjustable nebulizer recommended for organics
o Fluorinated High Density Polyethylene Mark VI spraychamber recommended for both organics and aqueous solutions.
Performance Guarantee
Varian guarantees that an absorbance of 0.55 (4 s ) or greater can be obtained from a 5 mg/L copper standard using a Mark VI air-acetylene flame under optimized conditions with the mixing paddles removed. Factory studies of ten different units showed an average absorbance of 0.73 with a standard deviation of 0.044.
With the mixing paddles fitted and the impact bead adjusted, precision will be better than 0.5% from just ten 5 second integrations.
PC Compatibility
Spectr-AA-300/400 Plus software is certified for operation with 100% IBM AT compatible personal computers with 8086/286, 386 and selected 486 processors, with minimum 512 kbyte Random Access Memory (1 Mbyte RAM recommended if running third party software applications), DOS 3.30 or higher (but not with DOS Shell) and VGA monitor recommended. Consult with your Varian representative to confirm PC compatibility.
