Root cause analysis is used in almost all industries to find out the cause of the problems. It helps to improve the quality of product if it is used properly by the management because it gives the way to implement the corrective and preventive action.
Root Cause Analysis is the most important factor in determining the quality of each organization.It is a methodology of knowing the first action that leads to the sequence which in turn leads to the problem and finds a way to solve this problem.
The company auditors must observe the deviation and its relation with the past events,they  have to understand how could this intervention cause the deviation. So, Root Cause Analysis is used to know the reason for each deviation or bad results. 

Type of Root Cause Analysis Techniques.

1)      Group Thinking OR Brain Storming:
A group of experts meets together to find the exact cause of the deviation and find a solution for it.
Through this method a team discuss about the problem.

2)      Fishbone Diagram OR Cause & effect diagram OR Ishikawa diagram.
Fishbone diagram includes the potential cause of the problem and is used in
   order to find the real cause.It technique also called cause effect diagram,Ishikawa diagram and 6M method.It is called 6M method because machine,material,measurement,method,man power,mother nature technique including here.

3)       5 Whys: It is very effective technique. 5 Whys tool works as its name, you should ask yourself "why?" 5 times in order to get to the sequence that causes the problem.

These 3 techniques will get you near the real cause, and it will help you to know what are the changes that you have to do, where are your weak points, and also how to prevent the occurrence of this problem again.

Root Cause Analysis consume a lot of time and resources, so it is only indicated when you are very sure that an event has affected the organization badly and needs an action to be done.

To determine loss on drying (LOD)

To determine loss on drying (LOD) Definition:   Loss on drying compares the weight of product sample before and after drying. The result is the percentage of moisture in a product. % Moisture = (Begging weight-Ending weight) X 100                         -----------------------------------------------                                    Begging weight  Loss on drying determine by two method which is given below: Method (1):   Weigh accurately a dry empty glass Petri dish. Put the sample (about 0.5 to 5 gm as par requirement, Its mean if sample having less wet take 5 g weight. If sample having more wet than take 0.5 g weight ) in dish and weigh. Note down the reading. Distribute the sample in Petri dish by gentle shaking. Place the loaded dish (without cover) in the drying chamber for two hours. Maintain the oven temperature 105 +/- 5 0 C.  After drying is completed, open the drying chamber, cover the dish and allow it to cool at room temp.  Keep it in the desiccator for 15

IR स्पेक्ट्रोस्कोपी और इसका सिद्धांत

IR स्पेक्ट्रोस्कोपी और इसका सिद्धांत  IR स्पेक्ट्रोस्कोपी क्या है और इसका सिद्धांत क्या है? एक अणु या एक रासायनिक यौगिक में यह पता लगाने के लिए कि कौन से कार्यात्मक समूह या समूह मौजूद हैं, हम IR स्पेक्ट्रोस्कोपी तकनीक का उपयोग करते हैं। आईआर स्पेक्ट्रोस्कोपी तकनीक का प्रदर्शन करने के लिए हम विद्युत चुम्बकीय स्पेक्ट्रम की एक विशिष्ट श्रेणी का उपयोग करते हैं जिसे हम IR (इन्फ्रारेड) विकिरण कहते हैं आईआर विकिरण तरंग दैर्ध्य की विभिन्न श्रेणियों से बना है और IR विकिरण के इस अनुप्रयोग को IR स्पेक्ट्रोस्कोपी के रूप में जाना जाता है क्योंकि यह पहचानने के लिए कि सभी कार्यात्मक समूह मौजूद हो सकते हैं हम IR विकिरण का उपयोग करते हैं इसलिए जब हम किसी नमूने पर आईआर विकिरण लागू करते हैं, तो हम इस तकनीक को आईआर स्पेक्ट्रोस्कोपी कहते हैं  अब आइए नजर डालते हैं आईआर स्पेक्ट्रोस्कोपी के सिद्धांत पर   जिस किसी भी नमूना का हम विश्लेषण करना चाहते हैं (नमूना किसी भी रूप में हो सकता है - ठोस, तरल या गैस) हम उसका नमूना तैयार करते हैं और इसे आईआर स्पेक्ट्रोफोटोमीटर में डालते हैं IR स्पेक्ट्रोफोटोमीटर वह उपकरण है

Karl Fischer (K.F.)

Karl Fischer (K.F.) Karl Fischer (KF) titration is water determination techniques which is industrial scientists. It is performed by volumetric or coulometric measurement techniques. Principles of Karl Fischer titration: The KF reaction is based upon an early reaction called the Bunsen reaction, in which sulfur dioxide is oxidized by iodine with the consumption of water during this oxidation. German scientist Karl Fischer published a method in  a year 1935 for determination of water content in samples. This was a titrimetric method based on Bunsen re action used for determination of sulfur dioxide in aqueous solutions. The original reaction is as below: SO 2 + I 2 + 2H 2 O → H 2 SO 4 + 2HI The KF titration reaction currently accepted is as follows, and was reached by several advances in understanding the mechanism of the reaction and modification of the original reagent: The titration reaction is said to reach its endpoint once the iodine stops reacting with the
