New Compact Microspectrometer Design Achieves High Resolution & Wide Bandwidth

A new microspectrometer architecture that uses compact disc-shaped resonators could address the challenges of integrated lab-on-chip sensing systems that now require a large off-chip spectrometer to achieve high resolution.

Spectrometers have conventionally been expensive and bulky bench-top instruments used to detect and identify the molecules inside a sample by shining light on it and measuring different wavelengths of the emitted or absorbed light. Previous efforts toward miniaturizing spectrometers have reduced their size and cost, but these reductions have typically resulted in lower-resolution instruments.

“For spectrometers, it is better to be small and cheap than big and bulky -- provided that the optical performance targets are met,” said Ali Adibi, a professor in the School of Electrical and Computer Engineering at the Georgia Institute of Technology. “We were able to achieve high resolution and wide bandwidth with a compact single-mode on-chip spectrometer through the use of an array of microdonut resonators, each with an outer radius of two microns.”

Plenty of discussions are happening on LabWrench all the time. We have many questions come in daily from users that are seeking advice from fellow users and lab professionals on LabWrench. Can you help any of these users find the answers they are looking for?

How do I set up kinetic mode in Analytik Jena SPECORD® Plus 210 plus
I would like to determine urea in serum sample using urease-GLDH enzymatic UV method (DiaSys test kit). How do I set up the protocol for the test? After we mixed the sample and reagent, then OD1 should be measured; then again in 50 second OD2 will be measured (2 point kinetic measure). I need the value of OD1-OD2 (the difference) then multiplied by the fixed factor. This might be easy to measure using the protocol that is already available in the SPECORD Plus 210, but I would like to know how to set up protocol for a kinetic test. Help this member.

Cobalt and Iron interference in Spectroscopy
I want to know if there is an analytical method to quantitatively separate about 100 microgram per litre of Cobalt from about 50miligram per litre of Iron in the same liquid sample before analysis in an XRF spectrometry. Without separation, the K (beta) lines of Fe overlap the K (alpha) lines of Co hence the recovery of Co is only about 60%. I am interested in the Cobalt not the Iron. Help this member.

Atomic Absorption Spectroscopy - Thermo Fischer Scientific iCE 3000
We have used above mentioned instrument for metal Detection. We are facing problem while using Nitrous oxide and Acetylene gas combination. In Chromium and Silicon was tested we are using these gases. In this case we are not getting Absorbance while using the standard solution. We are checking the standard solution in other instruments it is ok - other parts like Nebulizer and Gas inlet areas are good. But still we are not getting absorbance. We consulted with our service person, and they said the Acetylene and Nitrous oxide combination the flame should be Red cone formation in without sample. But we are only getting Blue with mixed yellow color in without sample. Only red cone formation while the sample was injected. Sample also not getting absorbance. We are not getting correct solution. Help this member.
