Slide 7
SP76 Standard Value
• Provides an agreed-upon, understandable & accessible information database that benefits global Sample Handling System Stakeholders
Swagelok Circor Parker
• Leaves room beyond the agreed-upon elements of the standard for manufacturers to compete in the marketplace
AD 2011: Analysis Division SymposiumLeague City, TX, USA; 11 - 14 April 2011
Slide 8
SP76 Proposed Updates
• ISA re-opens a standard for review after 5 years of initial release of a standard
• A focus group has been working on several revisions since 2007
• Parker proposes inclusion of the clocking pin as an optioninto the reaffirmed standard
Proposal 1: Alignment pin receptacle added to device footprint for safety and reference point
AD 2011: Analysis Division SymposiumLeague City, TX, USA; 11 - 14 April 2011
Slide 9
SP76 Proposed Updates
• Parker proposes inclusion of the clocking pin as an optioninto the reaffirmed standard
Proposal 2:
Develop an Analytical Symbol library for devices used specifically in SP76 process analytical schematics, because…

SP76 Proposed Updates
• Parker proposes inclusion of the clocking pin as an optioninto the reaffirmed standard
A block around the symbol represents an SP76 device with agreed upon geometry , functionality
and nomenclature
Symbol Library: How it would work:
AD 2011: Analysis Division SymposiumLeague City, TX, USA; 11 - 14 April 2011
Slide 12
SP76 Proposed Updates
A “Porting Legend” would accompany the device symbol
Symbol Library: How it would work:
AD 2011: Analysis Division SymposiumLeague City, TX, USA; 11 - 14 April 2011
Slide 13
SP76 Proposed Updates
Porting Legend: Why??
• Conventional wisdom leads all three manufacturers to define the center port as inlet and offset as outlet
• Providing end users with field plug and play freedom!
Parker SwagelokCircor
AD 2011: Analysis Division SymposiumLeague City, TX, USA; 11 - 14 April 2011
Slide 14
SP76 Proposed Updates
Porting Legend: Why??
However, what if a competitive performance advantage can be achieved by porting differently?
Both SP76 Compliant, but is it still “Plug & Play” ?
Users deserve to know how devices are ported!
AD 2011: Analysis Division SymposiumLeague City, TX, USA; 11 - 14 April 2011
Slide 15
SP76 Proposed Updates Summary:
Start with a symbol:• To describe in real-
time how a system is operating!
AD 2011: Analysis Division SymposiumLeague City, TX, USA; 11 - 14 April 2011
Slide 16
Myths: Fact or Fiction?
Myth #1: The flowpath hole is too small!
The standard specifies a .110” ID (2.8mm) maximum flowpath hole
Conventionally plumbed systems are normally ¼” x .035” wall, resulting in a .180” ID or 1/8” x .028” wall, resulting in a .069” ID
.180” ID .110” ID .069” ID
.254”2 .0094”2 .0011”2
Hole Cross Section Areas
AD 2011: Analysis Division SymposiumLeague City, TX, USA; 11 - 14 April 2011
Slide 17
Myths: Fact or Fiction?
Myth #1Facts:1. Sample Systems are commonly populated with needle
valves to control flow and /or restricted orifices to control pressure. Such restrictions result in cross sections much smaller than .0094”2 .
2. Rule of Thumb: dozens of modular sample systems are in Low Sulfur Diesel systems flowing at 2-3SLPM.
3. Viscosity & Temperature Matters; obviously modular systems are not for all applications
4. Numerous papers have been presented regarding SP76 hole sizes; most notable can be found on the CPAC Website:

Myths: Fact or Fiction?
Myth #2: I Can’t followthe flowpaths!
A Very Fair Statement …
AD 2011: Analysis Division SymposiumLeague City, TX, USA; 11 - 14 April 2011
Slide 19
Myths: Fact or Fiction?
Myth #2: Fact
“Tight Design”
“Intuitive Design”
It’s a matter of design; what’s most important to you?

Myths: Fact or Fiction?
Myth #3: It’s Not Mainstream

Gen-1 Value, #3
Sounds Good, but…
AD 2011: Analysis Division SymposiumLeague City, TX, USA; 11 - 14 April 2011
Slide 23
Gen-1 Value, #3
…isn’t tighter better?
O-Rings are very forgiving!
AD 2011: Analysis Division SymposiumLeague City, TX, USA; 11 - 14 April 2011
Slide 24
Gen-1 Value, #2
Do we still use outdated tools?
When o-ring seal connectors are
available?
Why stop here?

Gen-1 Value, #1
Conventional Schematic
AD 2011: Analysis Division SymposiumLeague City, TX, USA; 11 - 14 April 2011
Slide 26
Gen-1 Value, #1
Conventional Schematic Gets Built
Sam builds according to his best judgment based on the schematic in January 2004
Joe builds according to his best judgment based on the same schematic in July, 2010
Will both systems be built indentically??
AD 2011: Analysis Division SymposiumLeague City, TX, USA; 11 - 14 April 2011
Slide 27
Gen-1 Value, #1
The unique system design also maintains its own top level part number if purchased as an assembly from your supplier
Modular system“schematic” drawings are both a schematic as well as a physical representation of the system.
