环境控制
Changes in laboratory temperature, relative humidity and even the presence of electrostatic charge have been identified as factors that can have a direct impact on the dose emission and aerosol generation performance of OINDPs, thereby compromising DDU and APSD test data integrity. We offer a range of environmental condition control solutions to help analysts improve the accuracy, sensitivity and reproducibility of inhaled product test data.

NGI散热器
Exacerbated evaporation caused by the thermal mass of the NGI may be an issue for devices such as nebulisers that deliver the drug as an aerolised solution. Loss of solvent reduces droplet size, producing artificially low particle size measurements and compromises the integrity of APSD data.

吸入器测试工作站 (ITW)
The hub of an inhaler testing system, the ITW is a modular workstation designed to aid handling and manipulation of the various pieces of test apparatus and accessories, improving workflow. The ITW offers analysts the flexibility to pick and choose the attachments necessary for their test set-up needs. Simply connect the required attachments and start testing with greater ease.

玻璃膨胀室
The majority of nasal products are designed to generate droplets/particles with a mass median aerodynamic diameter (MMAD) of greater than 10 to 20 microns. This is to increase nasal deposition and minimise deposition in the lungs. However, most sprays deliver a proportion (typically <5%) of fine droplets in the <10 micron range. It is important to quantify this Fine Particle Dose (FPD) since it can penetrate beyond the nasal tract and into the lower respiratory tract or lungs, which may be undesirable. Cascade impactors are designed to capture particles in the range 0 to 10 microns and are widely used for this application.
