Der volle Inhalt der QuelleCapillary electrophoresis (CE) has a wide range of applications in the field of analytical chemistry. In general the most expensive part in a CE system is the detector due to the fact that the detector must have a high sensitivity for small detection volumes and low concentrations. Building portable instruments is one way to make the instruments cheaper and has the advantage that they can be used virtually everywhere. However, downscaling of CE instruments puts some extra demands on the detector. This report describes the design and building of two homemade light-emitting diode (LED) based detectors; a LEDabsorbance photometric detector (LED-AP) and a LED-induced fluorescence (LED-IF) detector. The main goal was to install them inside a portable CE and make a simple separation. The performance of the two detectors had to be evaluated before the main goal could be achieved. p-Nitrophenol was used to create a sensitivity graph for the LED-AP detector, calculating the upper linearity to 5.6 mM when the sensitivity had dropped 10 % caused by non-linearity. The sensitivity graph also showed that the detector had an effective pathlength of 74.2 µm and a stray light of 4.5 % for a 75 µm i.d fused-silica capillary. The LED-IF detector was evaluated by determining the limit of detection (LOD) for fluorescein, at a signal to noise ratio of 3. The LOD was 0.72 µM ± 0.01 µM when immersion oil was used to limit the light scattering from the optic fibres in to the capillary and 0.58 µM ±0.02 µM when silicone oil was used. Without doing any improvements only the LED-AP detector could be used in the portable CE. As a common application area for portable CE instruments is environmental analysis, indirect detection using p-nitrophenol as a probe for separating anions was done to test the system. All analytes were eluted in less than 4 minutes.

Der volle Inhalt der QuelleThe chlorophyll fluorescence (ChlF) is directly related to the photosynthetic process. However, at canopy level this physiological link between fluorescence and photosynthesis may be blurred by structural vegetation changes and geometrical effects linked to interactions between sunlight and the three-dimensional structure of the canopy. Furthermore, much of our knowledge about the relationship between fluorescence and the physiological status of plants come from leaf level studies carried out under laboratory conditions. The physiological significance of ChlF at canopy level and under natural conditions is still a major subject of research and a source of uncertainties in the interpretation of SIF. This doctoral project aims were: 1. To study chlorophyll fluorescence yield at canopy level: we describe a new instrument, Ledflex, which is a micro-LIDAR dedicated to perform continuous measurements of vegetation fluorescence yield. Ledflex has been successfully applied under full sunlight conditions to establish the signature of water-stress on a pea (Pisum Sativum) canopy. Under well-watered conditions the Fs diurnal cycle present an M shape with a minimum (Fmin) at noon which is higher than the fluorescence level observed at predawn (Fo). After several days withholding watering, Fs decreases and Fmin

Ethylene glycol monomethyl ether (EGME), ethylene glycol monoethyl ether (EGEE) and their acetates are broadly used as solvent in industries. Due to their satisfactory chemical and physical properties, they have been used in paints, lacquer, inks and semiconductor industry. They enter human bodies by ingestion, inhalation or dermal penetration and are metabolized to methoxyacetic acid (MAA) and ethoxyacetic acid (EAA) by alcohol dehydrogenase and aldehyde dehydrogenase. The metabolites cause testicular atrophy, teratogenicity, hematological toxicity and carcinogenicity in human. The aim of our study is to provide a method based on capillary electrophoresis with indirect LED-induced fluorescence detection to determine MAA and EAA in urine. The background electrolyte providing optimal separation and maximum signal-to-noise ratio was consisted of 4 mM tetraborate buffer, 500 μM fluorescein and 10% acetonitrile at pH 9.20. The separation voltage was 15kV. The dynamic ranges of MAA and EAA were 5.76 - 345.45 and 1.07 -213.40 μg/ml with R-square of 0.9985 and 0.9992, respectively. The limits of detection for MAA and EAA were 0.83 and 0.46 μg/ml, respectively. The analysis of the urinary samples spiked with MAA and EAA were finished in 10 min, and the recovery of MAA was 95.4 - 98.8 % and that of EAA was 97.7 - 101.4 %. It showed that a simple, fast, and less expensive method for analysis of metabolites of ethylene glycol ethers in urine was developed.

Abstract The application of an ultraviolet (UV) light emitting diode (LED) to on-line sample concentration/fluorescence detection in capillary electrophoresis (CE) is described. The utility of UV-LED (peak emission wavelength at 380 nm, ~ 2 mW) for fluorescence detection is demonstrated by examining a naturally fluorescent (riboflavin) and a non-fluorescent compound (tryptophan), respectively. The detection limit for riboflavin was determined to be 0.2 ppm by the normal MEKC mode and this was improved to 3 ~ 7 ppb when a dynamic pH-junction techniques were applied. On the other hand, the detection limit of the tryptophan derivative was determined to be 1.5 ppm using the MEKC mode and this was improved to 3 ppb when the sweeping-MEKC mode was applied. In an analysis of an actual sample, the concentrations of riboflavin and tryptophan in beer and urine/milk samples were determined, respectively.
