3 Analytical Procedures for Chemical Control INTRODUCTION Analysis of the critical chemicals in photographic processing solutions may be used as a basis for discarding a solution or for adjusting the composition of a solution for further use. Examples of the routine use of analysis include certification of replenisher solutions, start-up and daily tank analyses, and the measurement of silver in fixers. Chemical analyses are also used for determining proper replenisher formulas with their corresponding replenishment rates. The cost of the chemical analyses may be small when compared to the cost of using a substandard processing solution or the cost of process downtime. The analytical procedures in this module are for analysis of chemicals in the solutions of KODAK Motion Picture Processes: ECN-2, ECP-2D, VNF-1 and RVNP. The numbers in the first column of the Table of Contents, identify the appropriate process for the procedure. A number with no letter prefix or the ULM- prefix, can be used with all Kodak film or paper processes. The ECN- prefix indicates the procedure is only for Process ECN-2 solutions, whereas ECP- procedures can be used for Process ECP-2D solutions. ECR- indicates use only with reversal Process VNF-1. The numbers are also assigned a suffix letter A, B, C, etc, indicating that the procedure is a revision of an earlier procedure or is based on an earlier procedure. The numbers found under the title of each procedure correspond to a Kodak internal system identifying the appropriate process. The procedures are as short and simple as possible, commensurate with the accuracy and precision that is required for adequate chemical control of the process. We recommend the laboratory and personnel be supervised by a chemist. The analyses may be carried out by a trained technician. Essential equipment includes an analytical balance, a pH meter (with suitable electrodes, buffers and filling solutions), thermometers, hydometers, magnetic stirrers, a constant-temperature water bath, and a spectrophotometer. A spectrophotometer equipped for making measurements in the ultraviolet and visible regions of the spectrum, provides a rapid means for making certain chemical analyses. Some models can also be used to check filters for sensitometers, densitometers and printers. This module also includes some procedures for noncritical chemicals, and a collection of standard analytical practices which are not usually required for routine control. These may be used as a basis for diagnosing processing troubles as they arise. These practices are generally used by the supervisors and technicians in charge of the maintenance of analytical equipment. Instructions for the preparation of the required reagents are given in Module 4, Reagent Preparation Procedures.
