Abstract: The present invention relates to a bioanalytical device (1), comprising: a housing (2) comprising an internal space (20) configured to accommodate a carrier (3) at a certain location, the carrier (3) carrying a moist medium (30), a humidity sensor (4) configured to measure a humidity in said internal space (20) and to provide an output signal indicative of said humidity, and an analyzing unit (5) operatively connected to the humidity sensor (4) so as to receive said output signal, wherein the analyzing (5) unit is configured to derive from said output signal a change of said humidity over time for detecting a presence of the carrier (3) carrying the moist medium (30) in the internal space (20) of the housing (2).

Abstract: The present application relates to a particle monitoring system, to a portable microbial air sampler, to a method for monitoring particles in a sample fluid, such as gases and particularly compressed gases, and to a method for calibrating/adjusting a particle monitoring system.

Abstract: The present invention relates to a system for calibration of a timer, comprising: a device (1) comprising a timer (10), wherein the device (1) is configured to conduct an analysis using the timer (10), wherein the device (1) is configured to calibrate the timer (10) of the device (1) based on a reference time interval TR expiring on a timer (20) of an NTP server (2).

Abstract: The present invention relates to a particle monitoring system and to a process of monitoring particles in a sample fluid.
