General Rules Within a Module, a Function Block can be used as many times as needed and in any order. Function Blocks can be built as sub-modules combining several functions on one block. Each Module does not require all Function Blocks. Some Function Blocks may be identical but serve different purposes, e.g. Block, Purge, Bleed. Underlined Function Blocks should be capable of being used as input sensors or outputs to a “Smart” diagnostic system. 11/24/2018

Matrix Philosophy There is no “standard” sample system design. This matrix model provides a macro list of Functional Blocks, capable of being fabricated by interested parties, which can be used to build a modular/field mounted/mix and match analytical system. Not all analytical problems can be solved by this model. The aim is >90%. The ASP Module is located at the pipe/process sample take-off point. The ARP Module is located at the piping/process sample return point. The S5 is ultimately intended for field (outdoor) installation. Immediate installations may serve in traditional settings (e.g. analyser houses) but in due time evolve to the field. Bypass Function Block will ultimately not be required since less sample is involved. The Validation Module provides QA/QC check of complete system operation via means of “smart” sensors and span and zero response checks. The S5 Module will be “smart” in the sense of being able to monitor F, P, T and initiate self-checking zero and span streams. (Refer to Smart Sample System document.) It will be self-diagnostic and predictive. The Validation Module should be a “standard”, non-vendor specific validation package. Function Blocks are intended to be Modular in concept i.e. plug and play and fit on a standard substrate (footprint) or bus. 11/24/2018

Matrix Philosophy (cont’d.) This matrix is classification system analagous to the NEC/CSA/CENELAC Electrical Codes, e.g. Class, Division (Zone), Group (or Dimension). It is a 3-dimensional matrix which provides a framework for classification of analytical components - both sensors and sampling components. The Interface Module provides data/diagnostical/analysis equipment control to the Control Center (DCS) and Need to Know Nodes (via Intranet/Internet). The Interface Module should provide a Standard/Global “fieldbus style” interface. The Controller Module allows setup and access from anywhere on the network (e.g. local to the apparatus or remotely). Ana.1 is a Function Block on the S5. Since this may take some time or be impossible in some cases to implement, a Function Block will be provided (Ana.2) to allow sample to/from an adjacent Analytical Module. Function Blocks should be designed for handling minimum amounts of sample decreasing the duty cycle on filters and other conditioning components. 10. The driving forces for this concept is simpler installations, faster delivery, more reliable data and ultimately lower costs. 11/24/2018

Sampling Engine A self-contained sampling device acting like a syringe. (X-proof). temperature and pressure control integral sample probe integral filtration isolation, bleed, back-purge automatic block, zero and span withdrawal and return of the sample from one location - no vent required supports the use of miniature analytical devices - a sampling platform!
