1.2. 490 Micro GC User Manual Communications 5 Typically the Ethernet address cannot be changed and is the permanent way of identifying a particular hardware device The Ethernet address consists of 6 pairs of hexadecimal digits Gateway This is one of several settings within the TCP IP configuration that identifies paths used to connect with Ethernet devices on a different subnet The Gateway is assigned an IP Address Hostname The host name is an alternate way of identifying a device that is friendlier to people Frequently the host name and the IP address may be used interchangeable IP address This is a unique number for each Ethernet device within the set of connected devices Two PCs may have identical IP addresses so long as they are not interconnected to each other through the Internet The IP Address consists of a series of four sets of decimal numbers between 1 and 255 that provide routing information used by the TCP IP protocol to establish a reliable connection Without the IP Address communications would be bogged down trying to establish connections to Ethernet addresses at unknown locations Patch cable A cable that is used to connect Ethernet devices to hubs switches or your company network Protocol A set of rules that govern how computers send and receive information RJ45 connector A telephone jack style connector used for a Universal Twisted Pair UTP hardware connection for 10 100Base T Ethernet connections

Manual The Micro GCs have built in regulators that can be adjusted to get a constant or programmed pressure control which once constant or programmed pressure control is obtained results in a constant or programmed flow through the injector column and detector The pressure range is from 50 to 350 kPa 7 to 49 psi This pressure sets a continuous flow of carrier gas of about 0 2 to 4 0 mL min depending on column length and type A typical pressure rise is 200 kPa min which will give a significant pressure increase during the run without excessive baseline disturbance In most cases baseline subtraction may improve the quality of chromatograms that suffer from baseline drift The injector has a built in 10 uL sample loop that is filled with the gaseous sample The pressure of the sample should be between 0 and 100 kPa 0 to 15 psi and the sample temperature within 5 to 110 C 5 C of the analyzer When the chromatographic data system sends a START command the vacuum pump draws the gas sample through the loop and the injector injects the gas sample from the sample loop into the gas stream A typical injection time is 40 milliseconds ms This equals an average injection volume of 200 nL Injection time will be rounded to a multiple of 5 ms A practical minimum value is 40 ms A value of 0 to 20 milliseconds might result in no injection 47 4 GC Channels Column A variety of column configurations are possible on the Mi
