The present invention relates to a gas detector cell unit comprising a gas cell, the unit comprising an outer housing providing access to the gas outside through a protecting filter adapted to making gas cell safe for use in explosive environments, i.e. a sintered filter, and the unit comprising means for detecting reduction in the circulation through said protecting filter.

Gas detector clogging detection

The present invention relates to a gas detector cell and cell unit for optical detection of a predetermined gas, the cell being provided with optical means for investigating a gas sample present in the cell. The cell is constituted by a volume enclosed in a container, at least part of the container wall being constituted by a membrane, the membrane being provided with openings allowing diffusion of gas therethrough, and the membrane openings being provided with a catalyst for converting the gas diffusing therethrough to said predetermined gas.

Gas detector

A process vessel containing both an evaporation zone for evaporating a liquid feed and a treatment zone for treating the resulting vapor comprises an injector having an orifice, the orifice being in the evaporation zone, at least one evaporation surface for evaporating feed and generating vapor, the evaporation surface being located in the evaporation zone, wherein the injector orifice and the evaporation surface are positioned to prevent the formation of a drop at the orifice, a treatment zone for treating the vapor and at least one heater associated with at least a portion of the process vessel.

Process vessel with integral evaporator

The present invention comprises an apparatus and a method for mass analyses of an array of samples contained in distinct sample holders. The sample holders are placed on a plurality of sensors which preferably comprise an array of microbalances providing output signals comprising mass data on the array of samples.

Method and apparatus for mass analysis of samples

A process of forming an array of powder samples arranged in predefined locations where all samples have a flat surface in a common plane has been developed. A main support having at least N perforations from a first surface of the main support through a second surface of the main support in predefined locations. The main support is equipped with a flat support temporarily attached to its first surface. All samples are loaded simultaneously. A flat surface of each sample, where the flat surfaces are a common plane, is formed by forcing the samples within the perforations against the flat support. The samples are retained in position within the perforations against the flat support using at least one cover. The flat surfaces of the samples are in predefined locations and are all in a common plane.

Process of parallel sample presentation

A process for simultaneously testing a plurality of catalysts using combinatorial chemistry has been developed. The process involves containing the plurality of catalysts in an array of parallel reactors with each reactor containing a bed of catalyst. Each bed of catalyst is then simultaneously contacted, at reaction conditions, with a reactant to form an effluent of each reactor. The reactant or an inert fluid is at a space velocity sufficient to fluidize the catalyst beds. Each of the effluents is analyzed.

Process for simultaneously evaluating a plurality of catalysts

An apparatus and a method for rapidly generating a plurality of isolated effluents have been developed. A specific embodiment involves screening a plurality of solids through simultaneously contacting the members of the plurality with a fluid, sampling the resulting fluids, and processing the resulting fluids to, for example, determine changes as compared to the feed fluid or as compared to other resulting fluids.

Elevated pressure apparatus and method for generating a plurality of isolated effluents

An apparatus and a method for rapidly generating a plurality of isolated effluents have been developed. A specific embodiment involves screening a plurality of solids through simultaneously contacting the members of the plurality with a fluid, simultaneously sampling the resulting fluids, and processing the resulting fluids to, for example, determine changes as compared to the feed fluid or as compared to other resulting fluids.

Apparatus and method for generating a plurality of isolated effluents

An apparatus and a method for rapidly generating and processing a plurality of isolated effluents have been developed. A specific embodiment involves screening a plurality of solids through simultaneously contacting the members of the plurality with a fluid, sequentially sampling the resulting fluids, and processing the resulting fluids to, for example, determine changes as compared to the feed fluid or as compared to other resulting fluids.
