A spray pattern (SP) test is one of the most challenging in vitro tests for nasal spray products (NSPs) associated with a high degree of variation. The total results variation observed in such studies should be in major part representative of product performance to assure high confidence when making conclusions based on obtained results. Analytical methods should be developed in a way to minimize variation contribution of random factors. A systematic statistical assessment of sources of variation is encouraged to be performed during any method development.

Rapid development and global cultivation of genetically modified (GM) crops necessitated the use of analytical tools that detect GM crops throughout the product life cycle. Antibody-based immunoassays...
Quality by design (ICH-Topic Q8) requires a prospective summary of the desired quality characteristics of a drug product. This is known as the Quality Target Product Profile (QTPP) which forms the bas...
The development of functional and nutraceutical foods comes from a greater awareness of the relationship between food and health by consumers. In the last years, the idea of purify and encapsulate bio...
Vitamin K1 (phylloquinone) is one of the vitamin Ks. Several studies have previously investigated the role of vitamin K1 status in respect to disease, but without consistent results. Since vitamin K d...
In this study, paper-based ionization techniques-paper spray ionization (PSI) and paper spray chemical ionization (PSCI)-were evaluated and applied for high-resolution mass spectrometry (MS) based ana...
The goal of this non-interventional study is to investigate the efficacy and tolerability of an Ectoin containing Rhinosinusitis Nasal Spray (SNS01). Within the study, SNS01 will be used e...
Intrauterine device (IUD) insertion is a procedure that can cause pain. Fear of pain during IUD insertion is a barrier to use of this method. Currently, there is no recommended standard me...
We propose to assess one method of sperm selection based on the characteristics of spermatozoa recently introduced: Sperm Selection Assay, which used a gradient of concentration of progest...
The objectives of this study are to compare the efficacy and safety of DFD01 Spray to Vehicle Spray for topical treatment of moderate plaque psoriasis
This Phase 3 study (Study 305) has been designed to determine and compare the efficacy and safety of 188-0551 Spray and Vehicle Spray applied twice daily for up to four weeks in subjects w...
A CHROMATOGRAPHY method using supercritical fluid, usually carbon dioxide under very high pressure (around 73 atmospheres or 1070 psi at room temperature) as the mobile phase. Other solvents are sometimes added as modifiers. This is used both for analytical (SFC) and extraction (SFE) purposes.
Devices that cause a liquid or solid to be converted into an aerosol (spray) or a vapor. It is used in drug administration by inhalation, humidification of ambient air, and in certain analytical instruments.
The technique of maintaining or growing mammalian EMBRYOS in vitro. This method offers an opportunity to observe EMBRYONIC DEVELOPMENT; METABOLISM; and susceptibility to TERATOGENS
An analytical method used in determining the identity of a chemical based on its mass using mass analyzers/mass spectrometers.
An analytical method for detecting and measuring FLUORESCENCE in compounds or targets such as cells, proteins, or nucleotides, or targets previously labeled with FLUORESCENCE AGENTS.
