PLEASE NOTE: Before processing your first CBS blade order, Restek will contact you.
With hundreds—even thousands—of samples awaiting screening analysis in your lab, fast and reliable results are crucial. For many applications, sample preparation coupled with a chromatographic method is used to screen all samples. However, a new technological advancement is changing workflows and offers unprecedented speed to screening applications. Restek is redefining rapid-screening analysis with coated blade spray (CBS) technology. A coated blade is an easy-to-use sample preparation device that couples directly to a mass spectrometer for qualitative or semiquantitative analysis, providing truly rapid screening without the need for chromatography.

...Without Needing Chromatography for Every Sample?
The Future of Rapid Screening
With CBS technology, the same device can quickly and easily collect a sample and ionize that sample via electrospray ionization. Rapid screening workflows that once required complex, distinct, sample preparation methods and chromatographic separations are reduced to a few simple steps. And your most powerful analytical tool—chromatography—is reserved for only select samples that need additional analysis.

What Exactly Is "Coated Blade Spray Technology”?
Simply put, coated blade spray technology is a powerful tool for rapid-screening applications.
COATED Blade Spray TechnologyThe technology leverages the principles of selective partitioning of analytes of interest from water and other solutions or semisolid samples into a specially designed coating that has been deposited on a stainless-steel substrate. These coatings preferentially allow analytes of interest to partition quickly and effectively from a sample while preventing larger, matrix-related compounds from partitioning into the coating, resulting in a cleaner sample because matrix-related compounds are easily rinsed off prior to analysis. For initial release, Restek coated blades will be offered with a hydrophilic-lipophilic balanced (HLB) sorbent coating. Over time, a wide variety of coatings will be introduced to tailor the technology to different applications. Coated BLADE Spray TechnologyThe blade is a precision-machined, stainless-steel substrate for the specialty coating. This robust device has been designed and manufactured to be handled throughout the sample preparation process and, more important, to facilitate the effective ionization of the analytes prior to MS analysis. The stainless-steel blade is able to efficiently conduct the high voltage necessary to generate the electrospray that leads to ionization, and the pointed tip has been engineered to effectively balance the task of loading a sample onto the blade while also creating a properly formed and directed electrospray cone. |

Coated Blade SPRAY Technology
What allows CBS technology to be a direct-to-MS tool is its ability to collect and enrich a sample on a device that can also be used to create an electrospray, ionizing the sample, and introducing those ions into the MS for analysis. The formation of the electrospray is a result of the application of high voltage to the stainless-steel blade after a solvent has been added to partition the analytes of interest back into solution. Once the voltage is applied, the solvent forms a classic Taylor cone. Because of the pointed design of the blade tip, the Taylor cone is directed precisely towards the inlet of the MS analyzer, efficiently and effectively creating and transferring ions for mass analysis.
Coated Blade Spray TECHNOLOGY
The coated blades themselves are only a part of the full realization of coated blade spray technology. An ionization interface is required to allow you to couple the coated blade directly with the MS, and Restek is currently developing these CBS interfaces for multiple models of mass spectrometers. Novel multiplexing devices will also allow for the collection and sequential introduction of many samples into the MS, with the goal of automating the entire system to further increase workflow productivity. But, it all starts with a coated blade as the heart of a direct-to-MS technique that will revolutionize rapid-screening analysis.
