Support bracket
For easy mounting, incl. support for 8 gas connections consisting of:
- Mounting part: Dimensions: 380 mm x 110 mm (WxH)
- Bracket for gas connection; dimensions 146 mm x 110 mm (DxH)
Bracket on right side, mounted at right angle
The bracket is stipulated in the manual.
Exception
The bracket is not required if the MicroSAM is fitted in a protective casing approved by Siemens. In this case, however, shipping of the unit is only permissible in this protective casing.
Sample streams
For up to 4 sample streams (including calibration stream); e.g. 3 sample streams + 1 calibration stream; controlled by 4 internal digital outputs (relay contact 0.4 A / 24 V DC)
Pos. 8_0: For gaseous sample
This position contains a basic unit prepared for integration of the analyzer modules.
Pos. 8_8: Standard UKOG
Individual customers standard.
Pos. 9_B: Workstation operating software
The workstation operating software can only be ordered together with MicroSAM. Workstation operating software is required for each gas chromatograph network.
C01 – Method development and application
Comprehensive and specific development of the method is required for the tasks.
The measured components and switching functions are entered completely using a customer sample (or a specially selected calibration gas). Proof of repeatability is carried out in accordance with the customer specification.
If a natural gas analyzer for calculation of the calorific value is ordered, the evaluation parameters are specifically optimized for the natural gas analysis.
The required BASIC programs (H0X) are installed in the gas chromatograph.
The retention time window C6+ is set to the measured components n-C6 to C9.
J0X – Acceptance and customer information
The scope of delivery is checked and the documentation and operation of the device explained in detail during the factory acceptance.
This also comprises presentation of the analytical solution including communication, chromatograms, piping plan and gas path plan. If present, inspection of the sample preparation and discussion of the documentation are carried out.
Please supplement the order for J02 to J04 by the desired option from E0x.
Only experienced MicroSAM users should consider the option for starting up the MicroSAM in the context of remote acceptance, e.g. using a telephone conference (on request).
E0x – Repeatability test
Proof of repeatability over a period of 2 h is included as standard. Longer proof of repeatability for the unit can be ordered using the supplements E02 to E04.
F01 – Data transmission over Modbus
Implementation and testing of a Modbus table for Modbus communication (RS 232 / RS 485 RTU).
K0X – Inputs/outputs via I/O Extender
The MicroSAM basic unit provides four digital inputs and outputs. If more interfaces are required, these are provided by the I/O Extender. It should be noted, however, that the I/O Extender requires two device-internal digital inputs and outputs. The I/O Extender solution can generate up to 12 additional analog outputs for the chromatograph (further inputs and outputs on request). The latest generation of NESSI components for sample preparation can also be controlled. The max. cable length between MicroSAM (including master cable) and I/O-Extender must not exceed 20 m. A 24 V DC power supply is required for the I/O Extender. This must be provided separately, but can also be covered by the power supply of the MicroSAM.
Note:
If the delivery is to include a protective casing from the Set CV range, please refer to this category in Catalog PA 01. There you can find more information on the I/O Extender and its specification within this total solution.

H0X - Various calculations and functions using BASIC interpreter integrated in the GC
The BASIC programs are either preset ex-works or can be created and modified by the customer.
H01 – MicroSAM BASIC Editor
The MicroSAM BASIC Editor allows individual programming of calculations and functions by the user.
H02 - Application setup: Natural gas - calculation in accordance with ISO 6976-95
The following physical variables must be calculated in accordance with the standard: calorific value, heating value, Wobbe index, density, relative density.
The calorific value is calculated as standard in MJ/m3 on a molar basis referred to the reference temperature 25 / 0 °C (combustion/metering temperature). Calculation on the basis of other reference variables or tables (in accordance with the standard) requires unambiguous specification by the customer.
The BASIC program is preset ex works; a customer modification is only possible with the supplement H01.
H03 - Application setup: Natural gas - calculation in accordance with GPA2172-96
The following physical variables must be calculated in accordance with the standard: calorific value, relative density and compressibility factor.
The calorific value is calculated as standard in BTU/ft3 (S) referred to the reference temperature 60 °F. Calculation on the basis of other reference variables or tables (in accordance with the standard) requires unambiguous specification by the customer.
The BASIC program is preset ex works; a customer modification is only possible with the supplement H01.
H04 - Application setup: Natural gas - calculation in accordance with GOST22667-82
The following physical variables must be calculated in accordance with the standard: calorific value, heating value, Wobbe index, relative density.
These parameters are calculated based on the physical properties of the pure components. As a special feature, the methane concentration is defined as the residual value in this operating mode.
The BASIC program is preset ex works; a customer modification is only possible with the supplement H01.
H05 - Application setup: Customer-specific calculations and functions
An unambiguous description of the task is required in order to guarantee correct functioning of the program.
The BASIC program is preset ex works; a customer modification is only possible with the supplement H01.
The supplement H03 is only possible together with C0X.
