  • Patent number: 9040306
    Abstract: The present invention relates to a high-temperature furnace for T(O)C measurement of a sample, which has a furnace housing which bounds a vaporization space and has a sample opening for the dropwise introduction of the sample and at least one flushing opening for introduction of a flushing liquid. According to the invention, the furnace housing is lined with a spinel ceramic on an inner side facing the vaporization space. By means of the spinel ceramic, the vaporization space is lined with a material which allows particularly high temperatures within the vaporization space and thus very complete combustion and is at the same time very resistant to temperature changes. This allows cleaning with a flushing liquid at essentially the operating temperature of the vaporization space and removal of deposited salts, in particular recrystallized organic salts, from the vaporization space in the flushing liquid in dissolved or undissolved form.

  • Patent number: 8920658
    Abstract: Methods and apparatus for desolvating flowing liquid streams while retaining temporal resolution of dissolved substrates are disclosed. A novel small-scale self-regulating spray dryer preserves temporal resolution while desolvating a liquid chromatography eluent stream and depositing the solute onto an optical surface for infrared spectrographic analysis. The liquid eluent is pumped through a heated nebulizer to create a high-speed jet of solute containing liquid and solvent vapor. This jet is directed circumferentially inside a hot cylindrical cavity. Centrifugal force causes the larger liquid droplets to travel along the outer diameter of the cavity. The cavity surface is heated to cause the droplets to film boil. Film boiling reduces droplet contact with the cavity surface thereby retaining the solute in the droplets. The solute temperature is limited by controlling the pressure into which the solvent evaporates from the droplets.

  • Patent number: 8617898
    Abstract: Quantification of vitamin D2, vitamin D3, and the monohydroxy and diihydroxy metabolites of vitamin D2 and vitamin D3, can comprise labeling analytes with mass spectrometry (MS) tagging reagents and performing LC-MSMS analysis of the labeled analytes. The labeled analytes can include a labeled standard and can have distinct retention times on a reversed phase column, as well as distinct masses. Under high energy collisions, reporter groups can be generated. The intensity or the peak area detected for each reporter group can be used for quantitation. In some embodiments, a one-step tagging reagent is used that is a dienophile-containing, labeled Diels Alder reagent.

  • Patent number: 8592222
    Abstract: A method for analyzing molecular pollutants of a fluid. From a calibrated flow of fluid, a combination of a measurement of a total amount of molecular pollutants and a determination of chemical compositions and relative amounts of the molecular pollutants by adsorption on materials is carried out. The determination of the chemical compositions and relative amounts advantageously occur after a threshold value for the total measured amount is exceeded.

  • Patent number: 8513022
    Abstract: A method for determining the amount of a chemical species in a sample, in particular the amount of weak acid dissociable cyanide or total cyanide in a sample, and an apparatus for performing said method. The method comprises the steps of: i) treating the sample to liberate the chemical species into a gaseous stream; ii) directing the gaseous stream to a scrubber; iii) absorbing the chemical species into a scrubber solution; and iv) determining the amount of chemical species absorbed into the scrubber solution, wherein any remaining chemical species not absorbed into the scrubber solution is directed or recirculated to the scrubber in the gaseous stream and step iii) is repeated to increase absorption of the chemical species prior to performing step iv).

  • Patent number: 8513026
    Abstract: When an atomic absorption spectrophotometer (AAS) or inductively coupled plasma (ICP) is used, samples must be introduced in a liquid state. Thus, sample decomposition by acids must be performed. Methods for decomposing samples using beakers or microwaves have caused several problems such as loss of volatile elements, excessive use of acids, emission of harmful gases, limitation of sample capacity and amount, and inconvenience of cleaning up. However, the present invention can treat many samples with one acid injection through gas condensation by both heating of a reaction container and air cooling of a collection pipe, wherein the reaction container is made of fluororesin (Teflon) or quartz. Also, if there are many samples, the samples can be treated at once. Furthermore, since the present invention can treat the samples with a conventional heating plate, the invention can be used at inexpensive costs.
