Staining of subfossil chironomid head capsules: a method for improving the extraction process from lake sediments and peat
chironomids stain biological
2021/7/26
Subfossil chironomids are regarded as a useful biological proxy for palaeoenvironmental research, but picking chironomid head capsules from aquatic sediments is extremely time-consuming.
Selective Spectrophotometric and Spectrofluorometric Methods for the Determination of Amantadine Hydrochloride in Capsules and Plasma via Derivatization with 1,2-Naphthoquinone-4-sulphonate
naphthoquinone-4-sulphonate amantadine hydrochloride
2009/9/4
New selective and sensitive spectrophotometric and spectrofluorometric methods have been developed and validated for the determination of amantadine hydrochloride (AMD) in capsules and plasma. The met...
FFT-Adsorptive Voltammetric Technique for Pico-Level Determination of Tetracycline in Capsules at an Au Microelectrode in Flowing Solutions
Tetracycline ultramicroelectrode continuous cyclic voltammetry flow injection analysis fast Fourier transformation
2010/4/16
This study illustrates a novel method for fast monitoring of tetracycline in flow-injection systems. The fast Fourier transformation, along with continuous cyclic voltammetry (FFTCV) at a gold microel...
Spectrophotometric Determination of Mexiletine Hydrochloride in Capsules Using Bromothymol Blue
Spectrophotometry Mexiletine hydrochloride Bromothymol blue Ion-pair
2010/4/22
A new spectrophotometric method based on the formation of an ion-pair using bromothymol blue as ion-pair complexing reagent was developed for the determination of mexiletine hydrochloride in capsules....
Loss of iron to gold capsules in rock-melting experiments
Loss iron gold capsules rock-melting experiments
2012/4/1
Gold is used widely for capsules in high-temperature rock-melting studies because it is generally
thought to absorb negligible Fe from silicate samples. However, we observed significant losses of Fe
