  1. Compound Management Sequenom Espir Kahatt

  2. Compound Storage • Mini tubes: small plastic test tubes that can be easily Frozen • Racks: mini-tube racks hold 96 tubes at a 9mm pitch • Storage: Racks of mini-tubes are stored at –20º C in Freezers

  3. Mini-Tubes 2D Barcode identifies compound in Database The Database also Tracks its content, volume and Location

  4. Mini-tube Racks Racks are stored at -20º C in Freezers RFID Tag: Stores Rack ID and 2D barcode information of all mini-tubes on rack

  5. Managing Compounds • Compounds Need to be re-arrayed after each screening campaign for secondary screening • Once in a while the Database needs to be verified • Accidents happen

  6. Mini-tube Sorting Station RFID and 2D barcode Reader

  7. Capabilities

  8. RFID Advantages • Throughput • It is faster to read RFID tags than the barcodes on the mini-tubes • Safety Factor • IF database goes down compound location can be easily recovered from RFID tags

  9. HMS 100 Passive RFID Tags 736 Bytes of memory

  10. Memory • 1 byte = 8 bits • 1 byte represents a number between 0-255 • An ASCII character needs one byte of memory (ASCII table can range from 0-255) • We needed to store 97- 10 digit numbers, if each digit is 1 character then we need 970 bytes of memory, HMS100 only has 738

  11. Memory (cont) • If we represent a 10 digit number as a number and not 10 characters then we only need 4.5 bytes of memory per 10 digit number, that means we need only need 436 bytes of memory to store 97- 10 digit numbers
