In this work, we investigated the role of the nebulizer gas flow in electrosonic spray ionization (ESSI), by systematically studying the relation between the flow and the ion signals of proteins, such as cytochrome c and holomyoglobin using ESSI-mass spectrometry (MS). When a neutral solution...
Montaser describe the change in transport of analyte to plasma with change in injector gas flow rate for a concentric pneumatic nebulizer in their text, Inductively Coupled Plasmas in Ananytical Atomic Spectrometry, 2d Edition, ch. 11, at pages 524-525 (VCH). Specifically, to promote combustion...
Essentially, an all pneumatic system is described which provides for a predetermined flow of fuel and oxidant to the burner. The invention compensates for the variation in oxidant flow due to nebulizer adjustments by adjusting the oxidant flow to the auxiliary inlet of the burner. The invention ...
Figure 9. Nitrogen oxide electrochemical sensor response and sensitivity: (a) the relationship of sensing current and the concentration of NO2 and (b) the effect of gas flow rate on the sensitivity of the sensor for various potentials of PANI/Au/Nafion working electrode.Reproduced with permission...
Addition of 1% N2 to the coolant Ar gas flow at a nebulizer gas flow rate of 0.95 dm3 min–1 can eliminate 40Ar35Cl+ and dramatically reduce 35Cl16O+ and 37Cl16O+, without losing sensitivity for a representative analyte, In. Addition of 3% N2 to the central channel gas flow, at a...
For each condition, four different positions of vibrating mesh nebulizer were studied: (i) next to the ventilator, (ii) right before humidifier, (iii) 15 cm to the Y-piece adapter and (iv) right after the Y-piece. Aerosol size distribution were calculated using cascade impactor. Nebulized ...

Improving introduction efficiency from the single % range typical for most common pneumatic nebulizers to near 100% easily achieved for hydride forming elements (see Chapter 2) provides a 20–50-fold increase in sensitivity and substantial, even if not proportional improvement, in LODs. Moreover, ...
Operation parameters: capillary voltage: 3500 V; nebulizer pressure: 45 psi; drying gas: nitrogen at 10 L/min; drying gas temperature: 250 °C; sheath gas flow: 11 L/min; sheath gas temperature: 350 °C; nozzle voltage: 0 V, fragmentor voltage: 175 V; skimmer voltage: 65 V; octopole...
Mist nebulizer versus heated humidifier on endotracheal tube patency in spontaneously breathing intubated patients: A prospective, randomized controlled trial Using a humidifier in intubated patients is now a standard of care as the humidifying effect of the upper airway is lost. We conducted this study...
