This article presents a spectrometer developed by one of the authors to make spectromet-ric analysis affordable to every secondary school. The project website details several school experiments in
We provide a relatively novel and inventive disintegration test apparatus, which works using ''Light Dependent Resistor (LDR) and Light
UV-Vis-NIR spectroscopy is used to identify compounds in drinks for quality control, track cell growth in bacterial culturing and measure the absorbance of hemoglobin absorbance in clinical research.
Orodispersible films (ODF) are single or multilayer sheets of suitable materials intended to liberate rapidly the loaded active substance in the mouth, forming a fine suspension or solution in
In this work, we studied the structure of vitamin D3 orodispersible films utilizing Fourier Transform Infrared Spectroscopy (FTIR) and Ultraviolet-Visible (UV–Vis) spectroscopic techniques.
The spectrometer has a fiber optic entrance connector (standard SMA, others possible), collimating and focusing mirror and diffractional grating. A choice of 16 different gratings with different dispersion and
Basically, a spectrometer is an optical system consisting of two lenses/mirrors that produces an image of the input slit on the detector. In between the lenses/mirrors is placed a diffraction grating which
An efficient, cost effective microspectrometer that consists of a two-dimensional absorptive filter array of 195 different colloidal quantum dots is
Spectral data with frequency in time domain are gathered for example for purposes of spectrometer calibration in the method proposed by Faber et al. and in the wavelength mapping procedure
Recent studies have reported miniaturized spectrometers based on van der Waals heterostructures. Here, the authors demonstrate multifunctional SnS2/ReSe2 heterojunction
Introduction to Absorbance Spectroscopy single beam spectrophotometer is comprised of a light source, a monochromator, a sample holder, and a detector. An ideal instrument has a light source that emits
This unique design method covers a wide spectrum from UV to SWIR using only one imaging spectrometer without splicing systems or researching wide-spectrum detector, which allows
If the spectrometer has a large spectral range, it may also have filters to stop higher order light from reaching the sensor. Most optical spectrometers operate over the UV, visible, and infrared (or near
s, and services for liquid-, sample-, and cell handling in laboratories worldwide. Its product range includes pipettes and automated pipetting systems, dispensers, centrifuges, mixers, spectrometers,
This study describes a 2000 IU Vitamin D3 ODF for daily intake, consisting of hydrophilic polymers and suitable excipients, manufactured by film-casting process.
In the present study, in-depth review of the available body of data published on ODF development and characterization was performed. In total, 112 papers published between November
Texture plugin is designed to analyze the ODF (Orientation Distribution Function) from pole figure data measured with 0D or 2D detectors.
We report the design of a high-efficiency spectrometer for high-resolution spectral-domain optical coherence tomography (SD-OCT). The
This study aims to examine the vitamin D3 ODF structure using spectroscopic techniques to analyze interactions with excipients like mannitol.
The external influences can cause the position of the optical elements inside the spectrometer to shift from their nominal position which in turn causes the spectrometer to go out of wavelength calibration
Because an ODF is disintegrated in the mouth, it can irritate the oral mucosa if it is strongly acidic and taste bitter if it is strongly alkaline. Therefore, the film is developed to have a neutral pH, or close to
On the following pages are shown two common spectrometer geometries; the transmission grating based and the crossed Czerny-Turner. Also, the figures defines the key design parameters of a
A spectrometer measures intensity of electromagnetic radiation at diferent frequencies / wavelengths In practical applications spectrometers have a finite frequency / wavelength resolution and a finite range
