On-line analysis in IC
Integral™ systems provide a versatile and adaptable approach to
on-line IC. An unsurpassed range of Reagent-Free™ IC (RFIC™)
systems and IC capabilities can be combined with configurable
sampling systems and adaptable off-the-shelf industrial enclosure
options. Configure solutions for the process R&D lab, pilot
plant, or production area. Focus engineering resources on
implementation; not on instrumentation design.
Integral sampling modules and enclosures can be configured with
ICS-5000 or ICS-2100 IC systems
all with eluent generation capabilities and inert PEEK™ flow paths.
Dual system solutions are available for increased throughput or
complex analytical methods.
- The Integral Migration Path™ approach to on-line
implementation means systems can be configured for bench-top
R&D studies, pilot plant remote wet-lab monitoring, or
dedicated plant floor installations.
- Versatile sampling and sample preparation capabilities provide
support for system multiplexing and core functions such as
dilutions, concentration, matrix elimination, and reagent
- Off-the-shelf enclosure options provide environmental
protection and industrial compliance, when and where you need
- Chromeleon® PA Process Analytical
software provides system control, status, reporting, and
connectivity with industrial control systems using industry
standard OPC protocol.
- Support for PAT systems is based on nearly 25 years of
experience in a wide range of industries worldwide.
Typical analyzers are configured with one or more IC and RFIC
systems, all analyzing the same sample in parallel. Each of these
systems performs a specific IC or HPLC analysis.
An analyzer can be configured to handle from 1 to 21 sample
streams. Sample streams are analyzed in series with the order and
frequency determined by the user through software control.
Each system is configured with an appropriate analytical pump,
detector, accessories, and set of analysis columns. These
components are determined by the specific analysis being run on the
Integral sampling modules and enclosures
SP Sample Preparer
The Integral SP Sample Preparer provides versatile capabilities
for sample preparation before chromatographic analysis. The SP is
designed for continuous monitoring applications. Standard functions
include sample and standard selection, preparation, and loading.
Pressure, flow, and pH monitoring and dilution vessel heating are
available options. The SP can be utilized with Dionex bench-top IC
systems or within industrial systems configured with AE and LE
SS Stream Selector
The Integral SS Stream Selector provides a full-featured module
which automatically selects from up to 21 process streams for
sequential analysis. The SS can be configured to deliver samples to
up to four IC systems running in parallel. Sample streams can be
configured to run to waste or sample recovery, deadhead at the SS
valve, or recirculate back to the process.
Analyzer Enclosure (AE)
The Integral Analyzer Enclosure (AE) provides an adaptable
housing for a variety of IC or HPLC system configurations.
Stainless steel construction provides compatibility with harsh
operating environment, as well as, the value of a long-lasting
investment. The AE is designed for NEMA 12 / IP65 areas in its
basic configuration. Options are available for configuring for NEC
C1D2 / EU Zone 2 or NEC C1D1 / Zone 1 rated hazardous environments.
Optional air conditioning allows operation in a wider range of
The AE can be wall mounted or installed on a LE Liquids
Enclosure for a free-standing or wheeled unit. The AE also houses
the PC-based controller, flat-panel display, and touch mouse
device. Power input and automation connections are directed through
the top of the AE. Liquid and gas connections are directed through
the bottom and sides of the AE and LE.
LE Liquids Enclosure
The Integral LE Liquids Enclosure provides an optional base for
the AE as well as a means of isolating and protecting eluent,
reagent, and standards containers. It can also be used as an
expansion enclosure for additional LC modules. The LE is designed
to be NEMA 12 compliant, but can be configured for NEMA 4X / IEC
Automation and Control
Dionex-designed Chromeleon PA software provides configuration,
control, analyzer and system status, results display and trending,
along with user-defined alarm actions and results reporting. All
instrumentation is software controlled. All raw data is stored in a
secure database with audit trail support. Multiple levels of
security are available for access determined by the system
administrator. For applications in the pharma/biopharma industry,
Chromeleon PA meets the regulatory requirements of CFR 21, Part
