Nowadays the use of online SPE has shown important improvements such as higher sensitivity, analysis of smaller sample volumes, limited sample loss, no carry-over and robust and reproducible detection, while increasing sample throughput [23 27].
The Raman cross section of a normal Raman spectroscopy is inherently weak, thus preventing from the application of high-sensitivity analysis.
Therefore, a median of 850,000 events was recorded by FACS analysis to allow high-sensitivity analysis.
In high-sensitivity analysis where methylation of at least one gene was regarded as methylation, sensitivity improved to 90% while specificity was 64%.
Although FISH analysis of PLAG1 rearrangement in lipoblastoma does not show high sensitivity, combined analysis of both IHC and cytogenetic study may increase the diagnostic accuracy of lipoblastoma with unusual histology.
The developed method manifested several advantages of high sensitivity, short analysis time, low cost and easy of operation.
Besides reliable self-filling, the chip offers stable electrospraying and high sensitivity chemical analysis when coupled to a mass spectrometer (MS).
A dedicated analytical scanning transmission electron microscope (STEM) with dual energy dispersive spectroscopy (EDS) detectors has been designed for complementary high performance imaging as well as high sensitivity elemental analysis and mapping of biological structures.
Furthermore, the tracer is an inexpensive tracer (approximately 0.08 US$·kg− 1), which has higher magnetic susceptibility over two or three orders of magnitude than ordinary soils and high sensitivity of analysis (< 1% measuring error).
This is an attractive feature because it allows the use of a high flow rate (6 mL min−1) leading to high sensitivity and analysis speed, while keeping reagent consumption low.
