The development of a Time of Flight Secondary Ion Mass Spectrometer (TOF-SIMS) that can be attached to a FIB-SEM instrument provides an analyzer that very well complements the standard EDS detector. However, contrary to EDS, it gives much better depth resolution, possibility of depth profiling as well as distinguishing isotopes.

Special optical fibers doped by various optically active elements are becoming increasingly important for the development of fiber optic components, sensors, and lasers. The optimization of optical fiber manufacturing requires the monitoring of spatial distribution of doping elements within the optical fiber core.[详细]
The unique combination of an FIB-SEM system from TESCAN and a Time-of-Flight (TOF) Secondary Ion Mass Spectrometer (SIMS) from TOFWERK represents a novel and cost-effective solution for material analysis. The user of the system is provided with information on the material composition (including light elements) and distribution of individual elements in the analysed volume. [详细]
Nanoscale mapping is achieved by multi-modal correlative microscopy combining focused ion beam and scanning electron microscopy (FIB-SEM) with Time-of-Flight Secondary Ion Mass Spectrometry (TOF-SIMS).Mapping Li, Mn and Co nanoscale distributions reveals the micro-structural consequences of the electrochemical reaction, and allows identifying Li “trapping” sites within the structure

Diatoms are worldwide abundant unicellular microalgae (Fig.1). Their fossilized remains are the main component of diatomite, a mineral widely utilized in many differentindustries as an absorbent or additive. The chemical composition of the shells is critical for the properties of the final product. Therefore, there is a huge need to analyze the elemental distribution in the original diatoms. [详细]
Recombinant monoclonal antibodies (mAbs) have emerged as important therapeutic agents for the treatment of different diseases. This technology has been extended by the development of antibody drug conjugates (ADCs). [详细]
A preliminary assessment of environmental volatiles in water using static headspace analysis was performed using the Agilent 7697A Headspace Sampler, Agilent 7890B GC, and the Agilent 5977B GC/MSD system with high efficiency source (HES). The revolutionary design of the HES produces a higher ion currentyield for many compounds (greater sensitivity), which allows flexible approaches to sample analysis such as lowering detection limits, reducing sample size, speeding up analysis, and so forth.[详细]
The analytical requirements of the geological survey and mining industries are demanding in terms of high number of samples, number of elements, time/cost constraints and the difficult matrices. [详细]
