Sigma Laboratory

Nuclear Magnetic Resonance (NMR) Spectrometer


The NMR Spectrometer allows students to characterize organic and inorganic materials. As an important mode of analysis in the field of chemical synthesis, the NMR spectrometer enables students to carry out a greater variety of higher specialised research projects with greater depth.

Differential Scanning Calorimeter (DSC)

The DSC is a fundamental tool in thermal analysis and can be used in many industries such as pharmaceuticals and nanomaterials. It makes use of a thermal analysis technique that studies how a material’s heat capacity is changed by temperature. The DSC allows students to easily detect transitions in materials such as melts, glass transitions, phase changes and curing.


Scanning Electron Microscope (SEM) with Energy-Dispersive X-Ray Spectrometer

Students can make use of the SEM to generate high-resolution images of objects, as well as show spatial variations in chemical compositions. The SEM enables students to characterize their solid samples based on the texture, chemical composition and crystalline structure of their samples.


Cyclic Voltameter

SIGMA Labs is equipped with VersaSTAT4 Princeton Applied Research. This potentiostat offers students work on modern electrochemical problems that have critical impact on understanding reaction mechanisms, catalysis, electroplating, and other chemical phenomena underpinned by redox chemistry. Students and educators find this instrument particularly useful for their work. Wang Yuhang and Sim Yuki have leveraged the electro-analytical capacity of SIGMA Labs in their research work done in collaboration with IMRE (A*STAR) to investigate the degradation of dyes in wastewater effluent and to analyse the sensitivity of a biosensor for flaviviral detection.


High Performance Computing

From explanatory to predictive science, High Performance Computing is fast becoming the critical distinction in high impact research. Students have access to high performance computing facilities, both in-house at SIGMA Labs and externally in partnership with the National Supercomputing Centre (Singapore) and the A*STAR Computational Resource Centre. These students investigate a wide range of problems, from Group IV semiconductors and surfaces through to 2-dimensional materials, and have communicated their work at international conferences and science fairs, and publishing in peer-reviewed journals.


IR Spectrometer & UV/vis Spectrophotometer

Critical to synthetic chemistry is the capacity to characterise compounds. Further to NMR spectrometry, FTIR and UV/vis spectrometry is available for students to characterise organic and inorganic compounds, as well as materials adsorbed on surfaces.


3D Printers

3D printing offers students the opportunity to design and create solutions. Intricate to the design thinking framework, 3D printing prototyping allows students to actualise and build great ideas. A favorite among many groups, and extremely popular as a South Zone workshop for educators and teachers, 3D printing and MakerCentre@SIGMA Labs is fast becoming a key and critical facet of many research fields.
