Records notebooks

The Record of Invention. The second phase of developing a record of the invention is to condense the record into a summary form which serves several purposes. Specifically, the record of invention estabUshes a date of invention through attached copies of notebook records, spectra, and the like which all prove that the invention has in fact been conceived and reduced to practice in some form having practical utihty. 

The importance of an accurate and complete record of invention caimot be underestimated. The record of invention should serve as the basic document for estabUshing the date of conception and reduction to practice of the invention. The U.S. PTO issues patents to those who are first to invent. In a contest over inventorship, any available record of invention is submitted to the U.S. PTO to estabUsh proof of an inventor s rights. As of January 1, 1996, any inventor from a country belonging to the World Trade Organization may use such evidence before the U.S. PTO. Previously, this type of proof could be rehed upon only if the activity, documented in the notebook, record, etc, was undertaken in the United States. Similarly, activity undertaken after December 8, 1993 in Mexico or Canada may also be rehed upon to prove inventorship. 

Samples gathered and solutions prepared by laboratory personnel must be properly labeled at the time of sampling or preparation. In addition, a complete record of the sampling or preparation should be maintained. Sound quality assurance practices include a notebook record where one can find the source and concentration of the material used, the identity and concentration of the standard being prepared, the name of the analyst who prepared it, the specific procedure used, the date it was sampled or prepared, and the expiration date for any stored solutions. The reagent label should have a clear connection to the notebook record. A good label includes an ID number that matches the notebook record, the name of the material and its concentration, the date, the name of the analyst, and the expiration date. See Workplace Scene 2.5.

The first course of action would be for the analyst to inspect his/her technique, chemicals, notebook records, and perhaps the equipment used, to try to detect a determinate error. If a cause is found, then the measurement should be rejected and the reasons for such rejection documented. If a cause is not found, and if time is not a factor, it would be advisable to repeat the measurement, perhaps many times, to see if the anomaly appears again. If it does, the situation is not resolved unless a cause is established in the course of the repetition. If it does not appear again, its seriousness has diminished because there are more measurements from which the mean is calculated. 

Write all observations regarding the preparation in your notebook. Record the color of each supernatant and pellet. 

Which of these chemicals can you mix together without producing a chemical change In your notebook, record as many of these physical combinations as you can. 

Copy the table below into your notebook. Record the mass of the labelled beaker in your table.

In your notebook record all information relevant to this analysis column diameter and length, column packing, carrier gas and its flow rate, filament current, temperature of column, detector and injection port, sample size, attenuation, and chart speed. 

Be sure to keep a clear accounting of your procedure for the unknowns in your laboratory notebook. Record your observations for each test run for each ion in each vial. Remember, there is only one kind of cation and one kind of anion in each. As soon as you have identified a cation, no further tests are needed for other cations. The same is true for the anions. You should determine for yourself which tests are the easy tests and run those first. 

Because proper disposal requires information about the properties of the waste, it is recommended that all chemicals used or generated be identified clearly. In general, they must be retained in clearly marked containCTs, and if they have been generated within the laboratory, their source must be defined clearly on the container and ideally in some type of readily available notebook record. In academic laboratories where student tumova- is Irequent, it is particularly important that the materials used or generated be identified. This practice can be as important for small quantities as it is for large quantities of material. 

The American Chemical Society has prepared a record keeping fact sheet that gives guidelines for keeping a notebook record (see Document 1).
