TRANSCRIPT

  • Slide 1
  • GCAS OPERATION
  • Slide 2
  • FOOTPRINT
  • Slide 3
  • Footprint Access from View Footprint menu
  • Slide 4
  • Footprint RF Trend Shows the trend of RF in the correct order of RF from low to high Trend should be ascending
  • Slide 5
  • Footprint Correlation Chart Shows correlation between RF and molecular weight of saturated component For Daniel GC, correlation on the first two chart is expected to be higher than 0.995 The third chart will help troubleshoot in case of low correlation in the first two charts
  • Slide 6
  • Footprint Retention Time Shows the chart of retention time of each component
  • Slide 7
  • CALIBRATION DATA
  • Slide 8
  • Calibration Data Access from View Calibration Data menu
  • Slide 9
  • Calibration Data Features Features is exactly the same as footprint It shows calibration data in comparison to its footprint
  • Slide 10
  • FOOTPRINT / CALIBRATION DATA ACTION MENU
  • Slide 11
  • Action Menu When footprint or calibration data page is open, Action menu will be shown.
  • Slide 12
  • Action Menu Import Data Import data is to import GC generated final calibration report On Daniel GC it will be a text file of Final Calibration Report It is not necessary to do this if the GC is connected via Modbus
  • Slide 13
  • Action Menu Import Data CSV GCAS has csv format it recognize Historical data can be imported to GCAS using CSV file Both Calibration (RF and RT) and Mole% data can be imported
  • Slide 14
  • Action Menu Manual Entry Manual Entry is possible This is for data that is not available in electronic format to be entered manually Caution needs to be taken as there is no edit feature on footprint / calibration data page
  • Slide 15
  • Action Menu Set Status Status to each data can be set as following: Active / Inactive Inactive data will not be included in the trend Inactive data will not be included in uncertainty calculation Set flag Footprint data will be used as reference of calibration data comparison
  • Slide 16
  • Action Add Comment Each calibration data can be added a comment associated with it It can be error found or any finding regarding to the particular calibration data This can be used as audit trail
  • Slide 17
  • MOLE COMPOSITION
  • Slide 18
  • Mole Composition Access from View Mole Composition menu
  • Slide 19
  • Mole Composition Data is stored as normalized percentage Un-normalized percentage can be shown as a reference
  • Slide 20
  • MOLE COMPOSITION ACTION MENU
  • Slide 21
  • Action Menu When mole composition page is open, Action menu will be shown
  • Slide 22
  • Action Menu Spot Sampling It allows spot sampling data to be entered as mole composition Spot sampling will be shown as a dot in mole composition trending It will be compared against GC measured mole composition in the same trend
  • Slide 23
  • Action Menu Import Data CSV Historical data can be imported using a CSV file
  • Slide 24
  • Action Menu Set Status Mole Composition status can be set as active / inactive
  • Slide 25
  • Action Menu Set Status (Bulk) Many data from a period of time can be set as a bulk It is useful for instance in situation where there is platform shut down and therefore the data for the period is meaningless
  • Slide 26
  • Action Menu ISO 6976 Calculation It shows the ISO 6976 calculation for the particular mole composition Once in the page, other data can be selected from the same GC
  • Slide 27
  • Action Menu Add Comment Comment can be added to each mole composition
  • Slide 28
  • CALIBRATION GAS CERTIFICATE
  • Slide 29
  • Calibration Gas Certificate Access from View Calibration Certificate menu
  • Slide 30
  • Calibration Gas Certificate Shows the information of the calibration gas being used Historical data is also stored Provide information of uncertainty of each gas Information tab provide information of the bottle
  • Slide 31
  • CALIBRATION GAS CERTIFICATE ACTION MENU
  • Slide 32
  • Action Menu When calibration gas certificate page is open, Action menu will be shown
  • Slide 33
  • Action Menu New Certificate New certificate menu is to enter the calibration gas certificate data Both mole% and uncertainty to be entered Uncertainty value will be used to calculate overall GC uncertainty that can be accessed from another form Bottle information to be entered as audit trail
  • Slide 34
  • Action Menu Edit Certificate This feature is useful to correct any mistake on entered data Edit certificate feature has been added as it has been many cases where data was entered wrongly
  • Slide 35
  • Action Menu Set Status or K-Number Set status is to make the calibration certificate status active / inactive Inactive status will not be included in uncertainty calculation as well as multi level calibration / Single Point Calibration conversion Set k-number is to set the confidence level of uncertainty, k = 1 (68%); k = 2 (95%)
  • Slide 36
  • Action Menu ISO 6976 Calculator Provides ISO 6976 calculation for calibration gas composition
  • Slide 37
  • Action Menu Add Comment Provide comment for the particular calibration gas for audit trail
  • Slide 38

  • Data Analysis Access from View Data Analysis menu
  • Slide 40
  • Data Analysis The following is data Analysis Form
  • Slide 41
  • Data Analysis Select Parameter (RF) When selected parameter is RF, select component will determine which component will be trended. Single or multiple component can be trended in the same chart.
