Our name 24HourAnswers means you can submit work 24 hours a day - it doesn't mean we can help you master what you need to know in 24 hours. If you make arrangements in advance, and if you are a very fast learner, then yes, we may be able to help you achieve your goals in 24 hours. Remember, high quality, customized help that's tailored around the needs of each individual student takes time to achieve. You deserve nothing less than the best, so give us the time we need to give you the best.
If you need assistance with old exams in order to prepare for an upcoming test, we can definitely help. We can't work with you on current exams, quizzes, or tests unless you tell us in writing that you have permission to do so. This is not usually the case, however.
We do not have monthly fees or minimum payments, and there are no hidden costs. Instead, the price is unique for every work order you submit. For tutoring and homework help, the price depends on many factors that include the length of the session, level of work difficulty, level of expertise of the tutor, and amount of time available before the deadline. You will be given a price up front and there is no obligation for you to pay. Homework library items have individual set prices.
We accept credit cards, debit cards, PayPal, Venmo, ApplePay, and GooglePay.
Instrumental Analysis
As technology develops, machines that are able to detect previously unknown substances faster and more accurately are being constructed. Approximately 66% of all products delivered in the United States use chemical analysis of some sort. Instrumental chemistry is a field of chemistry that focuses on the modern machines and methodology used in chemical analysis. The two common methods of instrumentation are spectroscopy and mass spectrometry.
An instrument is a device providing communication between the system being analyzed and the person performing the analysis. Analytical lab instrumentation quantitatively and qualitatively interprets the physical and chemical characteristics of a sample. Qualitative methods reveal information about the sample on a molecular or atomic level. Quantitative method gives information in numerical form about the sample’s components. They typically need a source of energy in order to generate a response capable of being read.
The characteristic or property containing the information of interest is known as a data domain. Information is encoded in numerical form. Data domains are divided into non-electrical and electrical. Some examples of properties that may be measured are density, fluorescence, conductivity, and light absorption. A bit is the basic unit of information within the domain. Three types of analytical devices are detectors, transducers, and sensors. Detectors indicate or record any change in environment. A transducer changes information in nonelectrical domains to information in electrical domains and also does the reverse. Sensors are devices that allow for the observation of chemical species in a continuous and reversible manner.
A critical part of instrumental analysis is the calibrating of instrumental methods. Calibration establishes a relationship between an analytical response and the analyte concentration. It helps to endure that an instrument is operating correctly. Calibration may feature three kinds of limits: the limit of detection, the limit of quantitation, and the limit of linearity. The limit of detection is the lowest possible substance quantity that can be determined from the absence of that substance within a known confidence level. The limit of quantitation is the minimum amount of analyte by which someone can determine the difference between two different amounts of analyte. The analyte amount range by which a response changes is known as the dynamic range. A calibration curve is mapped on an x-y axis, with the solution concentration mapped horizontally and the variable being observed recorded vertically.
Microprocessors and microcomputers are computerized instruments. A microprocessor is a wide scale integrated circuit containing millions of transistors, resistors, and other elements. They are often used to implement operational control of analytical instruments. Microcomputers are made up of combined microprocessors providing functions such as timing, memory, and output. Computerized instruments in offline mode are mainly used to collect and transfer data to a computer for processing. An online computer can work directly and communicate with an analytical instrument. Most modern analytical instruments are embedded with capability to function with a computer. This inline operation allows information to be transferred to a computer at the same time that it is created by the instrument.
Instrumental analysis is often utilized in environmental, medical, and food industries. It is a way of providing assurance of a substance’s quality, safety, and consistency that affect people’s everyday lives. Rapid technological developments in the field continue to push this science into new and exciting fields.
Since we have tutors in all Instrumental Analysis related topics, we can provide a range of different services. Our online Instrumental Analysis tutors will:
With these capabilities, our college Instrumental Analysis tutors will give you the tools you need to gain a comprehensive knowledge of Instrumental Analysis you can use in future courses.
Our tutors are just as dedicated to your success in class as you are, so they are available around the clock to assist you with questions, homework, exam preparation and any Instrumental Analysis related assignments you need extra help completing.
In addition to gaining access to highly qualified tutors, you'll also strengthen your confidence level in the classroom when you work with us. This newfound confidence will allow you to apply your Instrumental Analysis knowledge in future courses and keep your education progressing smoothly.
Because our college Instrumental Analysis tutors are fully remote, seeking their help is easy. Rather than spend valuable time trying to find a local Instrumental Analysis tutor you can trust, just call on our tutors whenever you need them without any conflicting schedules getting in the way.
