進口m500型紅外光譜儀
m500 infrared spectrophotometer
●the m500 has a proven track record in industry for routine analysis, qa/qc and research as well as being one of the most popular educational systems around the globe.
●in the world of analytical spectroscopy where the phrase ft-ir is common, why does buck scientific, inc. still manufacture a true scanning infra-red system? the reason lies in the superb “hybrid" design of the m500 ir, which combines the fast-scan speed and high-energy throughput of single-beam ft-ir unit with the rugged capability of a monochromator-based optical system. buck can achieve equivalent resolution and speed without employing expensive beam-splitters made of moisture-sensitive kbr, moving mirrors mounted on costly bearings or delicate lasers prone to vibration damage. the m500 consistently proves its quality performance and economical reliability compared to ft-ir systems.
●the m500’s unique design and user-friendly software packages make it an ideal analytical tool for a wide variety of applications.
choose among an extensive range of ir sampling accessories to provide the capabilities to meet any laboratory requirement, making the m-500 package a complete, turn-key system at the most affordable price
●it provides its exclusive ez-scan software to allow the user complete access to instrument controls and for basic data acquisition. for more advanced applications, the grams/ai program provides sophisticated graphics manipulations and quantitative
report generation with the click of a mouse or a user-defined macro. the powerful spectral library search option lets you compare any sample spectrum to a data-base of known, reference spectra for a rapid qualitative identification of most unknowns.
the grams-based software has several useful supplemental macros to simplify routine and repetitive tasks; such as total petroleum hydrocarbon (tph) measurements or system validation for usp/nf and bp protocols with full cfr-20, part-11 compliance for the food, pharmaceutical and cosmetic industries. also available is an analog output of 0-1 volts for recorders or data-loggers who want to use the m500 as a variable wavelength ir detector for specific on-line applications and monitoring.
●our reputation for low maintenance cost and easy serviceability are built-in features of the m500 mechanical and optical design. from the high-energy ceramic glowbar irsource to the high-sensitivity dlatgs (deuterated l-alanine tri-glycine sulfate) solid-state detector with non-hygroscopic krs-5 windows, the m500 takes advantage of the most current electronic and optical technology. the ability for the end-user to perform basic maintenance and field calibration is another benefit not feasible with most ft-ir instruments.
in addition to its unbeatable price, the compact size and portability of the m500 is also a real plus! its small 20" x 24" footprint and lightweight construction saves bench space and enhances productivity for any laboratory.
●miracle is the first single reflection horizontal attenuated reflectance accessory (hatr) which combines the functionality of other single reflection products with the economy and flexibility of standard, multi-reflection horizontal atrs. this accessory offers several unique features including: choice of crystal materials – important for experiments requiring different spectral ranges; single crystal plate design for analysis of solid and liquid samples - an approach which lowers the cost of the accessory for those customers who have to deal with many types of samples. the accessory is an economical solution for users who want the flexibility of a single reflectance hatr. miracle - single reflection horizontal atr uses a “building-block" principle. the accessory consists of the universal optical base which can be fitted with a wide se-lection of sampling plates equipped with different crystal materials.
these crystal plates are kinematically mounted to eliminate the need for alignment and can be exchanged in a matter of seconds. the side of the plate features threads for a mounting ring designed to accept multiple sampling attachments.
●high optical throughput providing excellent sensitivity for analyses of a wide range of samples
