DropSens Newsletter
October 2017 www.dropsens.com
Dear Researcher,

In this newsletter we are presenting some examples that illustrate the potential applications of the SPELEC RAMAN equipment. This device is equipped with a laser of 785 nm, a bipotentiostat/galvanostat and a Raman spectrometer (Raman shift 0 2850 cm-1) all in a single compact instrument, which allows electrochemical techniques to be combined with Raman spectroscopy. Controlled by the powerful and user-friendly DropView SPELEC Software, it allows knowing in a quick, cost-effective, and effortless way, information about the structure of materials. Also we are showing the outstanding  Surface-Enhanced Raman Spectroscopy (SERS) effect  observed when working with this technique in combination with SPEs for quantitative assays.

STRUCTURAL DETERMINATION OF CARBON MATERIALS WITH SPELEC RAMAN

Raman Spectroscopy is a very attractive technique for material characterization which allows to know information about the structure of different materials.

The following example illustrates the suitability of this technique for the characterization of various carbon nanomaterials in terms of the sp2 and sp3 hybridized carbon atoms.

For this purpose, the Screen-Printed Electrodes refs. 110, 110SWCNT, 110CNT, 110OMC, 110GPH, 110CNF were placed in the suitable cell for SPEs ref. RAMANCELL coupled with the ref. RAMANPROBE (785 nm), which allows to perform the Raman measurements of the electrode surface at optimal focal distance. Find out more

ELECTROCHEMICAL SERS WITH SPEs

Ultrasensitive detection of chemicals species is an important issue in a broad range of scientific and technological fields. In this context, the SERS technique has been a great scientific breakthrough because, in contrast to Raman spectroscopy, it allows the detection of molecules in very low concentrations.

Studies carried out with the combined Raman/EC technique in disposable Screen-Printed Metal Electrodes (refs. C013 (Silver), 220BT (Gold), CU10 (Copper), SPCU10 (Silver/Copper)) show exceptional properties for SERS making them a much more sensitive and cost-effective alternative in comparison with other SERS substrates.

USUAL RAMAN VIBRATIONAL FREQUENCIES

SPELEC RAMAN facilitates the Raman spectroelectrochemical measurements, still the interpretation of data should be performed by the Researcher. In this application note, we describe the main vibrational frequencies for different functional groups and a probable intensity of the signal. Find out more
