Agilent Technologies Inc. today introduced the 7700 Series Inductively Coupled Plasma - Mass Spectrometer (ICP-MS) trace element analyzer. This successor to the world's best-selling ICP-MS, the Agilent 7500 Series, provides unmatched data integrity, is simple to operate and occupies the smallest amount of bench space by far of any ICP-MS instrument.

"ICP-MS analysis is becoming more routine while labs are measuring greater numbers of elements, to lower levels, in more challenging samples. And there's growing demand for higher quality data along with more throughput and easier operation," said Chris Toney, Agilent vice president and general manager, mass spectrometry systems. "We set out to design a totally new instrument that addresses these needs, and the early-access users tell us they're very pleased with the results."

The most obvious feature of the new 7700 Series is its small size, occupying just 73 cm of bench space. The mainframe footprint is more than 30 percent smaller than any other ICP-MS. Despite its small footprint, the 7700 Series sets a new standard for ICP-MS performance and ease-of-use in a rugged package.

Enhanced Collision/Reaction Cell Technology

Collision/reaction cells have been adopted as the industry-standard technology for removing spectral interferences in ICP-MS. Agilent's Octopole Reaction System (ORS), featuring helium collision mode, provides the most reliable and effective interference removal, especially for complex and unknown sample types. The 7700 Series features a new, third-generation cell (ORS3) that further improves the efficiency of helium mode, eliminating the need to use reaction mode (with reactive cell gases such as hydrogen) in almost all applications. This simplifies operation and eliminates false positives that frequently occur with reaction mode, thereby improving data quality.

The new collision/reaction cell, plus Agilent's unique High Matrix Introduction technology, which is standard on the 7700, make the instrument particularly well suited for complex sample types such as food, wastewater and soil digests. A redesigned ion lens improves sensitivity and reduces background noise across the mass range.

The 7700 Series features Agilent's new ICP-MS MassHunter software, which is easy to learn and use while offering the power and flexibility needed by routine and research labs. MassHunter is Agilent's common MS software platform, used across the entire family of Agilent GC/MS and LC/MS instruments, greatly simplifying staff training and support.

ICP-MS MassHunter incorporates many new productivity-enhancing features such as Expert Autotune, One Click Plasma Setting and Batch-at-a-Glance real-time data review.

To meet the growing requirement for speciation measurement, the 7700 Series easily connects to Agilent's 1200 Series liquid chromatography or 7890 Series gas chromatography systems. Now with MassHunter's fully integrated chromatographic data analysis, speciation measurement by ICP-MS has become truly routine.
