synthetic. Chromatography is the separation of two or more compounds or ions caused by their molecular interactions with two phases – one moving and one stationary (Weldegirma 2012). Three types of chromatography are used in organic chemistry: Thin Layer Chromatography (TLC)‚ Gas Chromatography (GC)‚ and Column Chromatography (CC). TLC stationary phase is a solid while the mobile phase is liquid. GC stationary phase is liquid and its mobile phase is liquid. CC is one of the most useful methods for

To: Wesley Clark From: Lizzie Heath Date: March 4‚ 2013 Subject: Thin-Layer Chromatographic Analysis of Drug Components (Experiment #15) The purpose of this experiment is to determine the components of an unknown drug and identify it as one of six (6) commercial drugs by using thin-layer chromatography. I added approximately a quarter of a tablet of acetaminophen‚ aspirin‚ caffeine‚ ibuprofen‚ salicylamide‚ and the unknown (#19) to separate test tubes containing 2.5mL of dichloromethane

One could personally see the switches connecting various computer nodes and may be a router to which the switches are connected. Also we can see the Network Interface Card (NIC) at the back of the computer where we plug in the cable with the RJ45 connector‚ the blinking light etc. on the card. (Sometimes when it is not

Unit 4 Research Project: MAC Sublayer The Media Access Control (MAC) is one of the sublayers contained in the Data Link Layer (DLL) of the Open Systems Interconnection (OSI) model. The MAC layer provides addressing and channel access control mechanisms‚ and works to transmit data from one Network Interface Card (NIC) to another across a connected network. Carrier Sensed Multiple Access with Collision Detection (CSMA/CD) is the process used by non-switched Ethernet to detect a clear channel between

Transfer the mixture to a centrifuge tube to separate the sample into layers‚ to help remove the water. Once the sample is finished spinning extract the organic layer and place in a test tube. TLC: To determine which mixture acetone and hexane is the best developing solvent the first step is to make mixtures of these solvents in test tubes. In the first test tube

building blocks of other biomolecules like proteins and ezymes (Davidson‚ 2015). This experiment examined a mixture of 3 amino acids. The purpose of this experiment was to identify amino acids in a mixture through cation exchange chromatography and thin layer chromatography. This was done by examining the amino acids elution order from a cation exchange resin based on their isoelectric points and their different

The show cdp entry command will list devices that have CDP enabled and if Layer 1 and Layer 2 are being used. The shop cdp neighbor command shows what is attached and it list the model and all software running on it. Hint: Read and study the
