SPECTROFLAME M120

ICP Bench-Top Spectrometer for Analytical Lines

from the Low UV (Cl, Br, 1) to the Alkali Elements

The SPECTROFLAME M120 from SPECTRO Analytical Instruments combines the best features of ICP spectro­meters with sonne new and extremely useful analytical benefits, all within a user-friendly System.

The result is a compact ICP OES instru­ment, developed for solving all ICP applications, while being simple to operate and at an affordable price.

The SPECTROFLAME M120 can meas­ure lines from 120 nm upwards. This affords the possibility of analyzing halogens (Cl, 1, Br), non-metals such as P and S, and many other elements at particularly sensitive and un-interfered lines (e.g. Ga, Ge and Si). The wave­length range 120 - 160 nm has not been thoroughly investigated to date and complete tables of spec­tral lines are not yet available. The user ofthe SPECTROFLAME M120 can detect previously unused lines in this spectral range, depend­ing on sample matrix and element selection.

Exceptionally high light transmission is ensured by using a minimum of optical components and efficient 100% total reflection optical surfaces.

All gratings used are of the master holographic type and all lines are measured in the first order, giving maximum sensitivity.

A variety of nebulizers and spray chambers is available to optimize the SPECTROFLAME M12O for specific analytical needs. These include pneu­matic nebulizers, Babington nebulizers for oils and samples with high

dissolved solids content, and HF resistant systems.

The SPECTROSONIC ultrasonic nebulizer is able to improve the detection limits by a factor of approximately 10 over pneumatic nebulization.

The Hydride Generator can be controlled by the SmartAnalyzer software such that an autosampler run can be analyzed with a pneumatic nebulizer and then automatically re-analyzed for hydride forming elements by using the Hydride Generator. Thus, maximum sensitivity is achieved for these elements.

The Autodilutor AD 25 automatically dilutes samples that are above range and then re-analyzes the samples. lt can also be used to auto­matically add an internal standard to all samples and to auto­matically spike samples.

The Autosampler AS 300 allows unattended Operation with com­plete automation of the QA/QC requirements for EPA Methods (e.g. 200.7). The system accommodates up to 300 samples.

The OLS converts the SPECTROFLAME M120 to a fully automated online system. Typical applications are the unattended, around­the-clock analysis of waste water streams, plating baths, etc.
