Spectrum Two EH D7066 分析系统

Efficient Hydrocarbon Analysis

This Spectrum Two^™ method-ready system is remarkably easy to use, assuring confidence in the generation of consistent quality spectra, every day. Compact, robust and completely transportable, samples can be run ion the Spectrum Two either in the laboratory or in a remote location, with no compromise in performance.

This out-of-the box solution enables labs to get up and running faster, regardless of the level of expertise. This comprehensive compilation of materials includes detailed SOP’s, sampling accessories, calibrations, and quick reference guides, all brought together through the Touch App^™ interface. This system includes:

• Environmental Hydrocarbons Application Pack
• Spectrum Two Instrument
• Spectrum 10^™ Software

Environmental Hydrocarbons Application Pack

The FT-IR Environmental Hydrocarbons Application Pack contains all of the resources and components necessary to perform efficient analysis using the Spectrum Two according to ASTM D7066 standards.

The Environmental Hydrocarbons Application Pack contains:

• 2 x Quartz Cuvette, 10 mm
• Cuvette Holder
• Environmental Hydrocarbons Touch Apps^™ Software Kit

The Touch Apps Software Kit includes the software and SOPs to support routine measurement of oil and grease in water and soil samples by FT-IR spectroscopy. Spectrum Touch software provides a simplified, workflow-driven operating environment; for faster, more reproducible analyses.

The Touch Apps software is included for the following methods:

• ASTM D7066 (2004) – Oil is extracted into a hydrocarbon-free solvent, and quantified by a transmission measurement.
• HATR method – Oil is extracted into a volatile solvent, and the solvent is evaporated from the HATR crystal.
• Cyclohexane method – Oil is extracted into cyclohexane, and quantified by a transmission measurement.

Spectrum Two Instrument

The Spectrum Two spectrometer with KBr optics and a standard, high-performance room temperature LiTaO₃ (lithium tantalate) detector delivers a spectral scan range of 8,300 – 350 cm^-1 whilst offering 0.5 cm^-1 resolution and 9,300:1 peak-peak signal-to-noise ratio for a 5 second scan in a sleek, compact design.

Key features that allow for consistent performance of this system include:

• Dynascan^™ interferometer – Fixed mirror-pair interferometer design does not require dynamic alignment to compensate for errors.
• OpticsGuard^™ technology – Unique humidity shield design protects Spectrum Two from environmental effects, allowing it to be used in more challenging conditions. Our long-life desiccant ensures maximum instrument uptime, regardless of where your analysis takes place.
• Atmospheric Vapor Compensation^™ (AVC) – Features an advanced digital filtering algorithm designed to compensate for CO2 and H2O absorptions in real time removing the need for instrument purging.
• Automatic Performance Verification^™ (APV) – Optional feature comprising an integrated, fully automatic filter wheel containing traceable reference materials and software allowing for abscissa, ordinate, noise, ASTM, and USP tests to be performed.
• Absolute Virtual Instrument^™ (AVI) – Optional AVI standardization using gas phase methane spectra ensures instruments are accurately calibrated. Unique standardization allows data to be transferred precisely between instruments, side-by-side or in remote locations.
• Sigma-Delta Conversion: The use of Sigma-Delta converters in the digitization of the FT-IR interferogram improves the dynamic range, reduces spectral artifacts, and increases ordinate linearity to provide accurate, reproducible results.

Spectrum 10^™ Software

Included in this system is the Spectrum 10^™ software, which enables you to control the instrument and to manipulate the spectra that you collect. The spectrometers can operate in ratio, single-beam, or interferogram mode.

From material and contaminant identification to quantitative analysis, the comprehensive Spectrum 10 software suite allows you to focus on what matters most – results. Designed for busy academic laboratories, this comprehensive FT-IR software package facilitates data collection, processing, results generation, basic and advanced data manipulation, spectral calculations, COMPARE spectral comparison, PLS/PCR/Beer’s Law predictions, Beer’s Law Quant method development, spectral search with starter libraries, and built-in online tutorials. The software enables users without scientific training to generate infrared spectra from a sample and validate them against reference spectra in minutes, or even seconds.
