Determination of Sulfur in Nasal Spray and the Raw Sulfur Salt
Determination of Sulfur in Nasal Spray and the Raw Sulfur Salt
3 Aug 2015There are a number of treatments available for the treatment of inflammation in the nose and throat, which all have different agent compositions, including sulfur. The use of spray bottles has been established for the application of the agent to the affected area. To ensure a consistent and safe dosage, the quality of the raw materials and final products must be controlled. In this application note, the sulfur content of different batches of nasal spray and the raw sulfuric salt was examined.

Atomic Absorption / Emission SpectroscopyAtomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) — also called optical emission spectroscopy (OES) — are used to detect the elemental constituents in samples. Both techniques involve the atomization of a sample. Atomic absorption spectrometers may use a flame or furnace to create an atomic vapor of the sample before irradiation with spectral light. Optical emission spectrometers may use a flame, inductively coupled plasma (ICP), microwave plasma (MP) or spark arcs to atomize and excite the sample. At higher excitation energies, electrons can be emitted instead of photons, which can be useful for samples that can’t be atomized and for surface analysis. Explore electron spectroscopy equipment such as Auger spectrometers and photoelectron spectrometers for surface elemental analysis of samples.

Drug delivery is often approached via the biopharmaceutical or small molecule drug's formulation, but it may also involve medical devices or drug-device combination products. Considerations include instrumentation, software and services. RegulatoryPharmaceutical regulations impact on all areas of drug development, manufacture and control and supply. Services are provided from the early stages of drug development and clinical trials through to dossier submission, approval and marketing. Regulatory also includes submission of analytical studies from the pharmaceutical product and safety. Quality ControlQuality control is needed in all production processes. Quality control is a monitoring procedure or set of procedures that are put in place to ensure that a manufactured product adheres to a defined set of quality criteria. SulfurPharmaceuticalsPharmaceuticals are medicinal drugs used in healthcare to diagnose, prevent, cure and treat illnesses. Pharmaceuticals that are excreted after use appear in wastewater and can have detrimental effects on the environment.
