摘要： The invention relates to a sniffing leak detector, which comprises a first suction line (14) in a sniffing probe (10), said line leading to a main device, and is provided with a larger second suction line (18), through which gas is taken in from the sniffing tip (11) by a gas delivery pump (19). By connecting the second suction line (18), the distance sensitivity is increased. By disconnecting the second suction line, the detection sensitivity is increased. Thus it is possible to first look for leaks with high gas throughput and subsequently exactly determine the leaks quantitatively with reduced flow.

摘要： A fast method for determining molecular mass using mass spectrometry has the following steps: specifying a first adjusting value (M1) of the mass spectrometer, recording the associated signal amplitude (A1), specifying a second adjusting value (M2) which is different to the first, measuring the associated second signal amplitude (A2), specifying a third adjusting value (M3) which is different to the first (M1) and the second (M2) adjusting value, measuring the associated third signal amplitude (A3), determining a quadratic function containing the measured amplitude values as y-values and the specified adjusting values as x-values, determining the maximum of the quadratic function, wherein the searched adjusting value is determined from the x-value of the maximum.

摘要： Disclosed is a sampling leak detector comprising a basic device (10) and a sampling probe (13) that is connected thereto via a tube (12). A display (17) is located on the sampling probe (13). A tactile display unit (22) is provided in a handle (14) while an acoustic display unit (33) is supplied on the basic device (10). The detector can be switched to a detection mode in which the color in the display (17) changes and the display units (22 and 33) are activated when a predetermined leakage rate is exceeded. The inventive detector can also be switched to a locating mode in which leakage rate data is displayed by means of a bar having a variable length and a sound is generated which has a parameter depending on the leakage rate data.

摘要： Normally a sniffing leak detector is calibrated for each test gas. The calibration concerns the arrangement of spectral positions in a mass spectrum and amplitude height. The inventive method consists in determining at least one mass peak by means of a calibrating gas and in determining the mass peaks placed between two mass peaks, for example between a zero point and a line, by interpolation or extrapolation. In such a way, it is possible to use the sniffing leak detector for a test gas which is not previously calibrated.

摘要： A method for the measurement of a gross leak in an at least partially incompressible test item (18) in a film chamber (12) having at least one flexible wall area, the film chamber being gas-conductingly connected to a pressure sensor (30), to a vacuum pump (26), and via a calibration valve (34) to a calibration chamber (36) enclosing a calibration volume (37), comprising the steps: evacuating the film chamber (12); measuring the pressure curve within the film chamber (12) upon conclusion of the evacuation; and gas-conducting connection of the calibration volume (37) to the interior volume of the film chamber (12) during the measurement of the pressure curve, wherein the pressure is measured before establishing the gas-conducting connection and during the gas-conducting connection to the film chamber (12), and wherein the pressure in the calibration chamber (36) is greater than or less than the pressure in the film chamber (12) before the connection to the film chamber (12). The method is characterized in that the pressure difference ΔPempty between the pressure before establishing the gas-conducting connection and the pressure during the gas-conducting connection to the film chamber (12) for an empty film chamber (12) without a test item (18) is compared to the corresponding pressure difference ΔPtest item when the test item (18) is contained in the film chamber (12).
