Purchasing Manual

Purchasing is an important activity for every business. Over time, purchasing has become a platform in building and maintaining relationship with other business units like suppliers and distributors. That is why it is important that the purchasing function of every business is well documented. This is when purchasing manual comes into the picture.  But what is a purchasing manual? This article will go through the definition and importance of this pertinent document.


Like user manuals, purchasing manual serves as guidelines between the purchasing department and suppliers in completing the procurement process. It provides all the necessary information both parties need to know and consider before engaging into the transaction.


This document provides the processes of the purchase transaction. It includes the request to purchase from the purchasing party, the completion of the request and all the specific and detailed instructions on how the purchase will be conducted.


Any purchase will not be completed if there is no payment need. Hence, purchasing manuals provides the policy payment of the transaction. It states the policy that both parties need to abide. In addition, the representatives from both parties who are responsible for the payment procedure should also be stated.

Delivery and Performance

Lastly, purchasing manuals should also include evaluation parts wherein both parties are given the opportunity to assess each other based on the completed transaction. It answers the questions, was the delivery successful? Was the performance fast and efficient? Simply, this part of purchasing document evaluates the overall purchase transaction.

In general, purchasing manuals guide the purchasing party and the selling party in the completion of a purchase transaction. This document is an essential element of any purchase as this implies as a contract that each party needs to follow and abide. It is an imperative that a purchase transaction is well documented.

Properties Of Water As Polar Molecules- A Theory To Note

Water is called as the ideal polar molecule component as the first thing we learn in our chemistry class, in the article, we will discuss the properties of water that commands it as the easiest way to understand the concept of Polar molecule. Water contains 2 molecules of hydrogen and one molecule of water that makes it universal solvent, you must hear the same during your school years. Before learning and going through details of water as Polar molecules let us know what the concept of polar molecules means exactly to know properties related to water better.

Polar Molecule- A quick go through

Polar in simple English means two different directions in exactly same manner means non-reacting and nonforming with each other. Polar molecules in scientific terms mean the same, it is net dipole concept that results opposing charges with slight positive charge and a bit negative charge arranged as we say in scientific term asymmetrically. Molecules are formed with electrons, protons, and neutrons, the easiest way to go remember Polar Molecule is to remember that unequal distribution of orbital is called Polar Molecule.

Why is Water Polar in nature?

Water as whole theory is neutral in nature but the arrangement of uneven distribution of Hydrogen with two molecules and oxygen with only one molecule makes it an ideal example to be called as a Polar molecule. Water is also called as a good solvent, chemistry gives the theory that molecules of water aligned with the positive end is very strongly glued and magnetized towards the two molecules. This is the clear cut reason why water is called as a good solvent.

Therefore the bottom line of the theory says sharing of electrons between Oxygen and Hydrogen as water forming agent forms covalent bond and an ideal polar molecule.

Things to Consider in Buying a Lie Detector

If you are planning to buy your own lie detector, one of the first things that you should know is that most of these are expensive. However, they are very reliable when it comes to knowing whether the person is telling the truth or not. There are lots of lie detectors that analyze one’s voice stress. But the interesting thing to that is that up until now, there is still no scientific study that proves this kind of lie detector.

For more information on lie detectors, you can visit liedetectortest.uk

One of the other things that you should consider is the skin resistance feature of the lie detector. This is a vital parameter because the principle followed by this is that a person sweats when he or she lies. When you lie, you feel a considerable amount of stress, thus you sweat.

Medical Connection

In medical terms, this is called psychogalvanic reflex. This happens that when a person is stressed, he or she sweats. The other parameters that are observed by a lie detector is the person’s blood pressure, pulse, and breathing rhythm. Though these parameters are redundant, they still enable the quick assessment and analysis whether the person is telling the truth or not.

Knowing the Parameters of a Lie Detector Test

This is the reason why not all of these parameters are necessary. If you are planning to buy your own lie detector, then you should choose one that measures one or two of the parameters mentioned. This would surely save you a lot of money. Another parameter is the measurement of one’s skin resistance. With this, you can just consider buying a low noise computer based skin resistance meter. It also has the same function with a lie detector.

Get A Psychic Reading For Free

There are a number of reasons why getting in touch with a psychic can benefit you in more ways than you can imagine.
