Often, you will not be able to take out a specific book.

To do this, here are a few helpful hints. Every single note card should contain ...

Neutral loss Neutral loss monitoring allows the detection of any compound that loses a specified mass during CID. This scan type allowed to detect any glucuronides (neutral loss of 176 Da), sulpho-conjugates (loss of 80 Da) and was helpful to identify molecules that lose a tropic acid moiety (loss of 166 Da) or a tropic acid-derived HCOH group (loss of 30 Da) [51, 52], The occurrence of the latter losses provided helpful hints for the presence of an (partly) unaltered tropic acid moiety in, e.g. atropine. 

The purpose of this paper is not to castigate library personnel, who have a difficult job and tend to be overworked, but to offer a few helpful hints which can extend the life of books and bindings and save money... 

The author wishes to thank Dr. J. Demaison and Dr. V. Typke for a critical reading of the manuscript and helpful hints. I also gratefully acknowledge the support by the Fonds der Chemischen Industrie.

Helpful Hints and Tips Radical Generation at the Fingertips... 

In the introduction to his invaluable French-English Dictionary for Chemists (5), Austin M. Patterson mentions some very helpful hints for the translation of organic compounds from French, where the prefix or suffix is the key to the correct translation. They are quoted here, with his kind permission, because as a rule they also apply to Italian. 

HELPFUL HINTS FOR CRITICAL EVALUATION OF STRUCTURAL INFORMATION... 

Helpful Hint Refer to the discussion of rounding off numbers on page 20. 

Helpful Hint Trailing zeros are ambiguous the next section offers a solution for this ambiguity. 

Helpful Hint Symbol x>y implies "x greater than y." Symbol x [Pg.25]

Helpful Hint Because most of the carbon is carbon-12, with very little carbon-13 present, the atomic mass should be very close to that of carbon-12. Approximations, before performing the calculation, provide another check on the accuracy of the final result. 

Helpful Hint Section 1.3 discusses the use of conversion factors. 

Helpful Hint Adding 2.016 and 16.00 shows a result of 18.016 on your calculator. Proper use of significant figures (Chapter 1) dictates roimding that result to 18.02. 

Helpful Hint When balancing equations, we find that it is often most efficient to begin by balancing the atoms in the most complicated formulas. 

Helpful Hint Note that each factor can be inverted producing a second possible factor. Only one will allow the appropriate unit cancellation. 

Helpful Hint Mass is a laboratory unit, whereas moles is a calculation unit. The laboratory balance is calibrated in units of mass (grams). Although moles are essential for calculation, often the starting point and objective are in mass units. As a result, our path is often grams —> moles —> grams. 

Helpful Hint Appendix A contains a review of the mathematics used here.
