Spectraline Inc. products

The ES series of spectrometer was developed by En’Urga Inc. and is marketed through Spectraline Inc. The spectrometer is used for analysis of combustion by-products and for emission and temperature measurements

The VS series spectrometer is a very high-speed visible spectrometer marketed by Spectraline Inc. The spectrometer is used for analysis of a wide range of phenomenon that involves radiation in the visible wavelengths (300-1000 nm).

The LS 200 is a mid-infrared line scan camera that is particularly suited for thermal imaging of fast moving objects. The LS 200 performs a dual-band line scan of radiation in the mid-infrared range of 1.2 to 4.8 microns. The high frame rate of 400 Hz enables the LS 100 to be used for a wide variety of online imaging applications. It can measure surface temperature without the need for user-supplied emissivity values. Dual wavelength capability also enables applications such as surface detection and measurement of moisture content.

The SS-100 scanner is used for obtaining spectra along a line.

The Spectra-Cart is a mobile platform specifically designed for the Spectraline family of instruments. It enables the user to move the instrument to various locations for measurements, and eliminates the set- up time needed for tripods, and for electrical connections. The Spectra-Cart provides power to the instrument from the battery power pack. All cables are neatly tucked away, freeing the cart and instrument completely.

The liquid sample to be measured is passed through the absorption cell. A broad band IR source emits radiation that passes through the sample and into the instrument. The path length is variable from 0 mm to 7 mm, and the diameter of the sampling chamber is 8 mm. In a typical application, a control panel is used to pressurize the fluid to approximately 100 PSI. The maximum allowable pressure for the flow cell is 150 PSI. The control panel is also used to supply cleaning fluid (distilled water for most applications) and air to purge the flow cell periodically. The flow rate through the flow cell depends on the viscosity of the fluid.

The fixed path length flow cells consist of precisely spaced sapphire windows in Teflon holders to withstand corrosion. A broad band IR source is used on an alignment platform to perform the transmittance measurements. The fixed path flow cells are connected to the liquid flow control panel which allows purging of the cell with cleaning fluid, and/or compressed air. The path length should be specified while orders are placed. Flow cells with sample chamber volumes ranging from a few microliters to several milliliters are available.

The FS100 Sample Feeder is used for management of sample flow through the flow cells. It has stainless steel tanks for holding and pressurizing liquid samples and purging fluids. It can be used with either the fixed or variable path length flow cells.

Gas flow cells are available in various path lengths. These can be used to measure compositon of gases. The gas can either be stagnant or continuously flowing through the flow cell. Multiple constituents in gas mixtures can be measured simultaneously.
