Avio 500 can look at high and low concentration analytes during same analysis - PerkinElmer

Avio 500 Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES)

PerkinElmer has launched an Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES) for high volume labs.

The Avio 500 is designed for analytical labs running high throughput multi-elemental inorganic analyses for a variety of sample matrices.

It is a compact benchtop instrument replacing the Optima 8300 ICP-OES as the high productivity model.

Avio 500 features

PerkinElmer said the Avio 500 features simultaneous background correction which means faster sample-to-sample time and improved data accuracy, matrix tolerance and the lowest argon consumption on the market for ICP. 

It offers a vertical torch and is able to handle difficult samples with accuracy and reproducibility.

The dual view capability allows the user to have minimal sample preparation and dilution, thereby reducing error. It runs at a 9 L/min total argon plasma flow.

Dual view optimizes axial and radial plasma viewing, measuring high and low concentrations in the same run, regardless of wavelength.

Customer challenges

Jim Corbett, EVP and president, discovery and analytical solutions at PerkinElmer, said customers can test across application areas while keeping up with the challenges of increasing sample loads and lowering analysis cost.

“Laboratory professionals continue to face an expansive set of challenges, as regulations increase in complexity and require testing for more elements, resulting in the need for higher sample throughput and a significant increase in the types of analyses they need to perform.”

Erica Cahoon, ICP product manager at PerkinElmer, said it gives the user flexibility to do a complete analysis with minimal sample preparation.

“The Avio 500 instrument can analyze a wide variety of food and beverage matrices by looking at the high concentration and low concentration analytes during the same analysis. Examples of high concentration elements may be calcium, sodium, magnesium while the toxic elements, chromium, lead, and arsenic are often found in trace concentrations," she said. 

“The Avio 500 is able to analyze high concentrations (parts per million and percent levels) and low concentrations (parts per billion) during the same analysis. When using the ICP-OES compared to the ICP-MS, the ICP-OES is able to handle high total dissolved solid samples at higher concentration.”

Combatting matrix interference

Cahoon said the biggest challenges customers face are fast analysis speeds, low ownership costs and lab space. 

“The Avio 500 instrument responds to these customer needs by offering: simultaneous background correction providing high sample throughput for the high productivity labs, low cost of ownership by running analysis at only 9 L/min argon total plasma flow and measuring 76 x 87 x 84 cm (W x H x D), the Avio instrument 500 frees up valuable space in the lab.”

The Avio 500 instrument has Universal Data Acquisition (UDA) which allows collection of all emission lines, whether or not predetermined in the method, with virtually no time or storage penalty. 

“UDA allows the user the flexibility to reprocess the data using a different emission line if the original wavelength chosen had an unexpected interference,” said Cahoon. 

“The Avio 500 instrument also corrects for interferences using Multicomponent Spectral Fitting (MSF), a mathematical algorithm that models the analyte and interference signal to improve detection limits and accuracy.

“Finally, the Avio 500 has the capability to do Interelement Correction (IEC). The IEC correction factor is a measurement of the effect of an interfering element upon the observed concentration of an analyte.”

The Avio 500 uses the cross-platform Syngistix software, to transition between AA, ICP and ICP-MS software. 

Meanwhile, PerkinElmer said last month it will acquire Euroimmun Medical Laboratory Diagnostics AG for $1.3bn.

Based in Lübeck, Germany, with 2,400 employees, Euroimmun does autoimmune testing and infectious disease and allergy testing. It is expected to generate $310m in revenue this year.

The transaction is subject to closing conditions and is anticipated to be completed in Q4 2017.
