The Detector: The separated ions are then measured, and the results displayed on a chart. Mass spectrometry has both qualitative and quantitative uses. These include determining the structure of a compound, quantifying the amount of a compound in a sample and determining the isotopic composition of elements in a molecule. This technique basically studies the effect of ionizing energy on molecules. It depends upon chemical reactions in the gas phase in which sample molecules are consumed during the formation of ionic and neutral species.
Tyler White CHEM151LL 32658 04/01/2018 Different Types Chemical Reaction Types and Equations Purpose: The purpose of this lab experiment is to examine different types of chemical reactions such as Decomposition reaction, Synthesis reactions, Combustion reactions, and different Chemical equations. The experiments were conducted online using Late Nite Labs. Materials: Because the experiments were conducted online there wasn’t any physical use of materials, only digital ones, for these labs to be performed. Only the registration for the website was needed to perform these online labs, as well as a desktop computer. Procedures: The first experiment was the Synthesis lab.
3. To purify and identify the product, recrystallization is used in order to purify the product, then melting point and TLC techniques are used to identify the product. Theory 4. In nucleophilic substitution reactions, there are two possibilities, either Sn1 or Sn2. In this particular experiment, an Sn2 reaction
The value of width and thickness entered into the programme of the machine. The specimen was placed in the grip of the testing machine and the grips were tightened. The extensometer was attached on the marks made on the test specimen. The initial load was tare. The speed of the testing machine was set and the machine was started at 5 mm/min.
Structural data can be created utilizing certain sorts of mass spectrometers, as a rule those with various analyzers which are known as tandem (pair) mass spectrometers. This is accomplished by dividing the specimen inside the instrument and analyzing the products created. This procedure is helpful for the structural clarification of organic compounds and for peptide or oligonucleotide sequencing. There are many different types of mass spectrometers but all uses magnetic and electric fields to exert forces on charged particles produced from chemicals to be analyzed. A basic mass spectrometer consists of three parts: 1.
Records of seismic waves allow seismologists to map the interior of the Earth, and locate and measure the size of these different sources. In this dissertation two different type of sensor are used for the frequency measurement (1) Accelerometer (Kinemetrics FBA-2 Episensor) (2) Short period sensors (Kinemetrics SS-1) [Passcal Instrument Centre]. Accelerometer: It also known as strong-motion sensors, are designed to measure the large amplitude, high frequency seismic waves typical of large local earthquakes, and operate in the frequency band 0 Hz to 100+ Hz. Kinemetrics FBA-2 Episensor: The Kinemetrics Episensor force-balanced accelerometer is a uniaxial surface package designed primarily for structural engineering applications. However, it can be used in a variety of applications for measuring accelerations up to ±4g and down to the ambient noise level.
The samples were analyzed in terms of the phases presented by the XRD. This will verify whether the different element composition temperature can affect the structure and phase transitions. In this study, the sample for XRD was take from welded part. The samples for XRD were cut according to the size of the sample holder where the samples were placed. The structure of the samples were detected and captured by a detector using copper (Cu Kα) as radiation source at a diffraction angle ranging between 20-90° in 2θ.
CHAPTER 3 METHODOLOGY This chapter discusses and focusing the procedure used to investigate the surface roughness and microstructure during medium turning of Ti-6Al-4V ELI using different combinations of cutting parameter values under dry conditions. Experimental tests were carried out using uncoated carbide. 3.1 Experimental Equipments During the experiment was conducted, it involves the use of several testing equipments, cylindrical workpiece, and uncoated cutting tool. All these equipment will be discussed in the sub topic. 3.1.1 Testing equipment a. CNC lathe Haas ST-20 The machine involve in this experiment shown in Figure 3.1.
