Abstract This study aimed to validate a wearable device’s walking speed estimation pipeline, considering complexity, speed, and bout duration. The goal was provide recommendations on the use of devices for real-world mobility analysis. Participants with Parkinson’s Disease, Multiple Sclerosis, Proximal Femoral Fracture, Chronic Obstructive Pulmonary Congestive Heart Failure, healthy older adults (n = 97) were monitored in laboratory (2.5 h), using lower back device. Two pipelines validated...

We present a new method for separation of enantiomers with high-field asymmetric waveform ion mobility spectrometry (FAIMS), coupled to mass spectrometric detection. Upon addition an appropriate chiral reference compound the analyte solution and subsequent ionization by electrospray ionization, formed diastereomeric complexes, which were potentially separable FAIMS. The methodology being developed is intended be general, but here amino acid analytes are specifically considered. In examples...

Abstract Direct coupling of micellar electrokinetic chromatography (MEKC) to mass spectrometry (MS) without employing partial filling is considered be a challenge. One way solving the problem would use an MS‐compatible surfactant. In present study, applicability series surfactants (sodium dodecyl sulfate (SDS), lauric acid, cholic acid and perfluorated carboxylic acids) have been investigated both in terms separation performance MS compatibility. It was found that MEKC system based on...

Abstract A chemometrics approach has been used for evaluating the effect of four experimental parameters when coupling capillary electrophoresis (CE) to electrospray ionization‐mass spectrometry (ESI‐MS). Electrospray voltage, sheath‐liquid flow rate, nebulizing gas and spray needle position in respect MS orifice were varied according a full factorial design. In addition main effects, two interaction effects could be identified as significant measuring peak intensity analytes, from sample...
