Abstract
The emitter clogging is the most common hardware failure of nano-electrospray ionization, to improve the durability and electrospray stability of fused silica emitters, we demonstrate a means of fabricating nano-electrospray emitters with controllable aperture size and gradually-narrowed channel on the tip. We simulated the fluid morphologies in the emitter channels by computational fluid dynamics and found more stable flow on aperture-controllable nano-electrospray emitter. Besides, we found the unstable flow sections of commercial emitters match the actual clogging sections very well, indicating the main cause of emitter clogging is unstable flow. We further tested the emitters by nano-LC-MS based proteome analysis. Compared with the commercial emitter, aperture-controllable nano-electrospray emitters promoted the total ion chromatogram intensity by 25%, the number of identified proteins by 6.58%, and the number of identified peptides by 7.87%. In total, 989 proteins were identified from 1 μg of extracted mouse cardiac proteins. After the optimization by using mouse samples, we analyzed clinical auricular dextral tissues from patients undergoing cardiac surgery and found 16 proteins related to atrial fibrillation. Overall, aperture-controllable nano-electrospray emitter exhibits better sensitivity and reproducibility in the application of nano-LC-MS cardiac proteome analysis.

Abstract
Here, a compact high-speed CE bioanalyzer based on a short capillary has been developed. Multiple modules of picoliter scale sample injection, high-speed CE separation, sample changing, LIF detection, as well as a custom designed tablet computer for data processing, instrument controlling, and result displaying were integrated in the bioanalyzer with a total size of 23 × 17 × 19 cm (length × width × height). The high-speed CE bioanalyzer is capable of performing automated sample injection and separation for multiple samples and has been successfully applied in fast separations of amino acids, chiral amino acids, proteins and DNA fragments. For instance, baseline separation of six FITC-labeled amino acids and ultrahigh-speed separation of three amino acids could be achieved within 7 and 1 s, respectively. The separation speed and efficiency of the optimized high-speed CE system are comparable to or even better than those reported in microchip-based CE systems. We believe this bioanalyzer could provide an advanced platform for fundamental research in bioscience and clinical diagnosis, as well as in quality control for drugs, foods, and feeds.

Abstract
The use of high quality fused silica capillary nanospray tips is critical for obtaining reliable and reproducible electrospray/MS data; however, reproducible laboratory preparation of such tips is a challenging task. In this work, we report on the design and construction of low-cost grinding device assembled from 3D printed and commercially easily available components. Detailed description and characterization of the grinding device is complemented by freely accessible files in stl and skp format allowing easy laboratory replication of the device. The process of sharpening is aimed at achieving maximal symmetricity, surface smoothness and repeatability of the conus shape. Moreover, the presented grinding device brings possibility to fabricate the nanospray tips of desired dimensions regardless of the commercial availability. On several samples of biological nature (reserpine, rabbit plasma, and the mixture of three aminoacids), performance of fabricated tips is shown on CE coupled to MS analysis. The special interest is paid to the effect of tip sharpness.
